A longtime Washington state couple took each other to have and to hold, for better or for worse – until Donald Trump forced them to part.

Gayle McCormick, of Bellingham, was shocked when her hubby of 22 years, Bill, mentioned during a lunch with friends that he was planning on voting for Trump during the primaries, Reuters reported.

The conservative Republican’s casual utterance was the “deal breaker,” she said.

“My jaw kind of dropped, and this was before the primaries, so it wasn’t even known yet who was going to be the nominee, and I didn’t speak for the rest of the luncheon and we didn’t talk about it,” said the self-described “Democrat leaning toward socialist.”

“I was incensed. I said, ‘I can’t believe that somebody I could be married to could vote for someone whose track record is so obviously poor in terms of civil liberties, his feelings about women, how he treats people in general,’” the retired California prison guard added.

Eventually, Bill changed his mind about Trump and wrote in former House Speaker Newt Gingrich in November — but Gayle had decided it was too late to make their marriage great again.

Now separated, Gayle said at her new home in Bellingham that she remains close to her ex whom she does not plan to divorce because “we’re too old for that.”

“It really came down to the fact I needed to not be in a position where I had to argue my point of view 24/7. I didn’t want to spend the rest of my life doing that,” said McCormick, who ultimately cast a write-in vote herself — for far-left icon Bernie Sanders, the Democratic senator from Vermont.

But she said she remains frightened – for herself and the country.

“I’m scared I have to find a new dentist. I have to find a new doctor,” she said. “Those are things that don’t seem like much, but when you’re 73 and you have diabetes and you’ve had a stroke, it gets scary to find new people and starting over.”

She added: “I think that women’s rights are in jeopardy. I’m really frightened at (Trump’s) cabinet choices.”

Other relationships have been upended by the election of the polarizing president.

A recent Reuters/Ipsos poll of 6,426 people in all 50 states found 39 percent of respondents have argued with family and friends over politics. Sixteen percent said they stopped talking to a family member or friend altogether.

But the poll also found that 21 percent said they became friends with someone they didn’t know because of the election.

The online poll, taken from Dec. 27 to Jan. 18, has a credibility interval — which is similar to margin of error — of 1 percentage point.
