There are only so many political arguments a marriage can withstand before it crumbles. Californian Gayle McCormick, 73, learned that firsthand.

She and her husband of 22 years separated after he “casually mentioned during a lunch with friends last year that he planned to vote for Trump,” according to Reuters.

“It totally undid me that he could vote for Trump,” McCormick told Reuters. “I felt like I had been fooling myself. It opened up areas between us I had not faced before. I realized how far I had gone in my life to accept things I would have never accepted when I was younger.”

Apparently, McCormick’s husband didn’t end up voting for Trump after all and wrote in former House of Representatives Speaker Newt Gingrich instead. McCormick also wrote in her vote for Democratic U.S. Senator Bernie Sanders of Vermont.

Despite this change of heart, McCormick moved into her own place in Bellingham, Washington. The couple does still intend to vacation together, despite their difference in views.
