AIBU to think that, in general, once you've got dc with someone, people will put up with more crap. Even crap they'd dump people for without a second thought if they didn't have dc with them? Like cheating for example.
Is this a good thing? It holds families together I suppose. If you can try to forgive and just get on with it, should you? Or if you'd have told him to get to fuck before dc, should you have the balls to say it now?
