I consider leaving my marriage at least once every couple of months when I am again in the doghouse for something I have done. It often coincides with holidays, birthdays and Christmas but can be any other weekend - he gets annoyed at some choice I've made (or a daughter has made) and we stop speaking for days. I've put up with it for years because I didn't want the children to live between two houses but they are now 19 and 17 and just see me as pathetic for putting up with what they see as his controlling behaviour. The problem is that the inbetween parts are good - I get on with him like no-one else in the world, we have so much shared history and I would be so much worse off financially. Plus all the aggro of the divorce and then living alone. So as not to dripfeed, I do have ADHD and have definitely behaved in ways that would justifiably make me a poor partner about 25 years ago before I started to understand myself and people's expectations of me, but this history seems to colour every interaction in the here and now. So, will I regret leaving my sometimes comfortable but sometimes miserable marriage? Did you?
YABU - You should leave a marriage that makes you sporadically miserable, you'll wonder why you didn't leave sooner
YANBU - You should consider whether divorce might just make you just as miserable but in a different house
P.S..Name-changed for this.
