1) Pray, a lot, for her leaders. It is hard in any circumstances when you cannot rely on them to do what your inspiration confirms.

2) If they unfairly deny a TR, that doesn't have anything to do with you. Your Heavenly Parents are not going to deprive you and your family of any blessing because of a leader. (This assumes that you have tried hard to see their viewpoint, and to be humble in seeking spiritual guidance in your search.)

3) The only thing a faithful member can do in these circumstances is to be the best example of discipleship that she can be.

4) It will be critical to address everything their family has chosen to live the Gospel, so she clearly knows what things she needs to continue doing because they are part of her covenant, and which things are negotiable. For instance, maybe you continue doing fhe, but only use the bible, or seek good things in other books of literature. (I read recently that someone published a Koran that has bible scriptures that say the same thing in it, designed to teach things that are universal across faiths, for instance. Since mormons believe the gospel incorporates all truth, a family search for truth does not detract from faith.) But you'll decline to agree to not wear your garments. You might agree to to something you've never thought appropriate on sunday afternoon, but not to skip church to do it. Etc.

5) It will be important as a spouse seeks to understand the other's objections to faith to seek original sources. Most of the time when you read that, instead of what someone says it says, you can see how it will support faith as much as it raises questions about the same faith. But just because someone says something is full and complete truth, especially in historical things, doesn't mean we actually know that. Both scientists and historians regularly revise what they once thought based on new information.

6) Mixed faith marriages that succeed focus on the things they still want and still believe that are the same, rather than on the ways they think differently. (For instance, if she doesn't have any increase herself, her bishop may agree that she has no tithing to pay. If the way they share the family income is that she does have some discretionary money, then maybe she tithes that. If she gets her own paycheck, she'll likely insist on paying 10% on that increase plus fast offerings. But she need not apologize for not being able to tithe on her husband's income if that is simply impossible.

7) Remember to honor your spouse as the precious child of God he still is and forever will be. Insist that he be fully respected as father, and personally supported. No putting down dad's choices because he no longer attends. (Though this doesn't require putting up with emotional abuse or trashtalking against your faith either.) Whether or not s/he ever regains faith, you may be the only expression of loving Heavenly Parents that s/he experiences on a day to day basis. Make it the best kind of discipleship you can deliver. There's a scripture in corinthians that says that a wife can sanctify an unbelieving husband. Everyone gets a full life to figure out their faith.

8 ) Try to separate relationship issues from faith ones. Often the two get so mixed up together that solving either becomes more difficult, if not impossible.

9) Unfortunately, she also needs to consult an attorney about her rights and develop a plan for going forward if dh (dear husband) decides to divorce her, or if his actions and words become too abusive for her to continue in the environment. I'm not suggesting divorce --- I don't believe that loss of faith is an acceptable reason for divorce. But when you cannot work into a relationship that is healthy, and separation hasn't been enough to repair the issues, or if spouse decides s/he cannot live with someone who continues to believe, having had a consultation can help stabilize the family and protect against decisions that will make things worse. For instance, if you don't have credit in your own name, you need to get it. If you've never worked, you may want to explore going back to school, or strengthening skills that might have commercial implications.

10) Kristy Money's workbook on mixed faith marriages can be helpful. There is also a private group on facebook called another testament of marriage, that supports people whose spouse no longer believes. At faceseast.org, there is lots of content about how spouses in her circumstance have dealt with all this. It is largely defunct, but the threads can be quite useful.

11) It will take some time, and living in such relationships isn't for wimps. But so living has two very great benefits. The first is that you get to learn what agency really means in God's great scheme and how it is critical to His overall plan, see how the atonement heals everything. The second is that you'll learn what unconditional love really is, and how to give it. While I would wish neither on anyone, both of these will make huge positive differences as you move through the really hard parts of living this reality.

12) Do your venting to people who are obligated by professional and legal duty not to tell anyone what you say. Family and friends have a hard time forgiving and may not allow for others to change.

13) Ask for good HTers and VTers. You may not get them. But ask for them anyway.

14) Remember that you have Heavenly Parents and your Savior as your biggest cheerleaders, and when you cannot walk it alone, They will carry you.

15) Do not let the stupidity of any leader or careless member stop you from keeping your covenants. Yes you may feel like you cannot accept every calling, or that must disclose any time or other limitations you'll have. But that is different from letting someone else's reaction or actions determine your destiny. Keep the faith no matter how hard it is to see someone else doing the things they do that are hard.
