In some couples, one partner is substantially more committed than the other. We call these Asymmetrically Committed Relationships (ACRs). No one who is looking for lasting love wants to find themselves in an ACR, but we suspect it has become increasingly easy to land in one. It doesn’t have to be this way.

Commitment and Power

Relationship scholars have long been fascinated by the implications of ACRs, although only a handful of studies examine the characteristics of these relationships.1

Decades ago, sociologist Peter Blau wrote at length about differential investment in a relationship. Following is a quote from his 1964 book:

“If one lover is considerably more involved than the other, his greater commitment invites exploitation or provokes feelings of entrapment, both of which obliterate love.”2

Decades before Blau wrote, Willard Waller coined the relatively well-known “principle of least interest” about power in relationships. This new principle was influenced by the writings of sociologist Edward Ross.3 Waller wrote:

"That person is able to dictate the conditions of association whose interest in the continuation of the affair is least."4

The principles Waller and Ross wrote about obviously hold true for any relationship, whether romantic, family, or business. In the social science literature focused on the nature of commitment, the same themes emerge.5 The person who is most committed to a relationship continuing has, in some important ways, less power than the one who cares less—especially if that partner could not care less. Blau drew to the nature of these relationships by putting them squarely into the framework of commitment, noting how differential commitment can obliterate love, as large differences in power often do.

In a study, "Asymmetrically Committed Relationships,"6 we, and our colleagues, examined asymmetrical commitment in the relationships of unmarried young adults.

Our Study

We used a subsample of 315 couples in our national, longitudinal sample of and cohabiting young adults in opposite- relationships, who are between ages 18 to 34.7 This sample allowed us to directly compare partners’ ratings on commitment (how dedicated one is to the future, to being a couple). We defined ACRs as those in which the partners differed by one standard deviation or more; thus, relationships were either ACRs or not, and within ACRs, there is a weak-link and strong-link partner.8 This assured that the couples we were analyzing as having ACRs had an important difference in partner levels of commitment. To get a feel for this, for a couple in which the average of the two partners was average, but with one high and one low, this would be like the strong link scoring at the 69th percentile on commitment, while the weak link scores at the 31st.

Our sample consists of couples in established but unmarried relationships who were together an average of just over two years at the start of the longitudinal study. Forty-one percent were living together, and 59 percent were not. There was a mutual commitment to marry in 47 percent of the relationships. In 24 percent, one or both partners had a child from a prior relationship, and 13 percent had a child together.

What did we find regarding the numbers of asymmetrical relationships?

65 percent of relationships were mutually committed, and 35 percent were not.

Men were much more likely to be a weak link than women (23 percent vs. 12 percent).

We have not always found such interesting differences between men and women on commitment in our studies on premarital cohabitation, but when we have found them, the differences always go in the direction reflected in this study. In non-married or premarital relationships, when there is a difference, men are more likely to be the less committed partner than women, by a factor of about 2:1.

One finding from our earlier studies seems especially relevant here.9 We found that there was no difference in the commitment levels of husbands and wives among couples who either only cohabited after being engaged or who waited until to move in together, but among those who had lived together prior to being engaged, there was a substantial difference in commitment between partners. Husbands in these marriages tended to be less committed than their wives, as well as less committed than men or women in relationships where the couples had only lived together after marriage or engagement. For these couples, the differences were strong before marriage and remained apparent and large years into marriage.

Before taking in some other findings, let’s reflect. Say you are considering marrying someone, but you believe they are less committed to you than you are to them. You may or may not marry this person, but if you do, you do not want to count on a trip to the altar to fix the gap in commitment. As we like to say, a transition is not transformation.

In our work on premarital cohabitation, we have tested the prediction that that moving in together before marriage or engagement is riskier than waiting until after that big question about commitment to the future is settled. Our concern is that people risk getting stuck in relationships they might otherwise have left, because cohabitation made it that much harder to break up.10 We have found support for that prediction in many samples with findings published in multiple journal articles.11 Based on this reasoning, we predicted that those who were currently cohabiting would be more likely to be in ACRs, because living together would make it more likely for these relationships to have continued. That is what we found.

Couples who were living together were significantly more likely (42 percent) to be in ACRs compared to those who were not living together (30 percent).

Similarly, we expected that those with plans for marriage would be substantially less likely to be in ACRs.

Couples with mutual plans to marry were significantly less likely (25 percent) to be in ACRs compared to those without mutual plans (45 percent).

That last finding must seem terribly obvious, but we were interested in it because of our belief that ambiguity about the nature and status of relationships has become such a strong part of how relationships form these days. Having mutual plans for marriage should be consistent with partners having both high and symmetrical commitment. Even so, we found this non-trivial percentage (25 percent) of relationships that were ACRs despite mutual plans for marriage. You might wonder how that could happen. Much of what we just wrote about cohabiting prior to being married, or at least prior to having mutual clarity to a future together, provides one explanation.

The Relationship Dynamics of Asymmetrical Commitment

We also looked at the relationship quality of ACRs versus non-ACRs. Both weak- and strong-link partners rated their relationships as having lower overall quality and as having higher levels of conflict and higher levels of 12 compared to those not in ACRs.

We found evidence that weak links’ ratings of poor relationship quality could easily be attributed to the fact of their low commitment, which makes total sense. First, people are less committed to a relationship that has problems. Second, relationships will have more problems when people are less committed.

The strong links’ patterns were more surprising. Typically, being highly committed leads to a greater inhibition of negative behavior and happier relationships, but not for strong links. These people tended to score very high on commitment (higher on average even than those not in ACRs), but they also reported lower relationship quality, more conflict, and more aggression—including aggression toward their partners.

These findings are consistent with what theorists such as Blau suggested: It is immensely dissatisfying and frustrating to be the more committed partner in an unequally committed relationship. That’s not a happy place to be. In fact, in a report we wrote a couple of years ago (Before “I Do”), we showed that those who had perceived, prior to marrying, that they were more committed than their partner reported lower marital quality.13 The perception of asymmetrical commitment was among the best predictors of lower marital quality once married.

Breakups

Not surprisingly, ACRs were more likely to break up than mutually-committed relationships. But curiously, ACRs in which men were the weak links were just as likely to continue as non-ACRs. In other words, relationships were not likely to end merely because the man was much less committed than the woman. The relationships most likely to end were those in which the woman was the weak link.

This finding was reminiscent of a few earlier studies, including some from decades ago, that examined differential levels of investment, love, or commitment between partners.14 We knew to test for this, but we were not sure how strongly to expect this finding, in this day and age.

Overall, women’s levels of commitment were vastly more predictive than men’s of who stayed together and who did not (five times more predictive). In part, we think this means that there are some men (by no means all or most) who are content to hang out with a woman they are not really serious about until that woman gets fed up. We will dig into that curiosity in a future blog. (And as one commenter noted, it is really not so curious that some males fit this pattern. It is somewhat more curious why the pattern persists.)

Are There More Asymmetrically Committed Relationships Than Ever?

We believe that asymmetrically committed relationships are more common now than at any time in the past 50 years. We cannot test or prove this by any data of which we are aware, but we believe it because of the following reasoning:

1. There has been a steady decline in cultural rituals and defined steps in the development of . Ambiguity reigns.

2. There is a growing preference for this ambiguity, because people rejection and fear that commitment is dangerous.

3. Important relationship transitions, such as moving in together or having a child together, now increasingly happen more from processes characterized by sliding than deciding. Deciding more often will reflect the formation and declaration of commitment.

4. This environment of mixed or confusing signals makes it easier than before to get deeply involved in—and stuck in—ACRs.

Think of it this way. With fewer cultural scripts and customs forcing commitment to be made clear (whether high or low, mutual or not), more people are finding themselves in long-term, unmarried relationships, sometimes for many years, before they come to realize that their partner is just not that into them. Sliding into moving in together or having a child together is often not transformative. The strongest commitments tend to be those that come about from decisions, particularly decisions people make while they still have full freedom to choose.

This presents a difficult set of circumstances for many young adults. Sure, it’s not usually wise to ask about your partner’s willingness to build a life with you on a second date (and we hesitate to use the word “date” since even that concept has fallen under the spell of ambiguity). But when the inertia for continuing a relationship is growing, it starts to be increasingly risky to avoid steps to determine if you both are on the same page.

A word of advice. If you are searching for lasting love and commitment, do not wait too long to find out whether you and your partner want the same future. We cannot say exactly how long you should know someone before pushing for more clarity about commitment—we just know a lot of people are waiting too long. And, as they wait, the less committed partner has strong reasons to avoid having “the talk” (read more here and here).

It’s painful to be hanging in with someone who is mostly just hanging around.
