How can be happy with these frequent fights? Unless he is the kind of person who just seeks drama. I can’t imagine people being happy with lack of peace in their life unless of course they are drama seekers. If he is one, then I see how he would be happy with it

I’d not trust what he claims. He claimed he agrees he is at fault in everything but then at the same time he was telling his coworker that you are to blame for things gone bad last time. He didn’t say that to you. What he thought and what he said to you didn’t exactly matched

It’s unusual for one partner be intensely unhappy and the other be perfectly happy all in the same relationship. But maybe it could happen.
