My ex and I divorced after ten years. It just didn’t work - I was not an ideal husband nor was she an ideal wife. But we worked together on the kids and they have all turned out okay - IMHO. Sometimes you just have to make the best of it. Do I wish we had had a happy marriage? Yes. I have eight siblings... half divorced at some point, half have already celebrated 30 - 40 - 50 year anniversaries. The kids... well, a mixed bag but all generally successful. C’est la vie.
My wife is one of four. Her brother is on #3, one sis has 4 exes the other married twice, widowed on second time.
My younger brother was gay (deceased), other married 50 years and a widower.
Our parents divorced after we two older kids had left home. My father stayed because my mother was so unstable and he knew in the 60s he’d never get custody. Needed to protect us.
