Is this a form of mental, emotional abuse?

I think so, but I'd also say, from personal experience, that it's probably best not to worry about whether something "qualifies" as abuse or not, because there are always going to be people who think you're making a fuss about nothing. The bottom line is, it hurt you, and that's not okay. less

I agree with this for the sake of this conversation. I'm really glad the OP is seeking help for the damage his actions had on her.

BUT...

There was bad behavior all around. She stayed when she was cheated on, when it doesn't seem that they were trying to work through it, especially since he denied that it had happened. She cheated too. She dated around and slept with other guys while she had a boyfriend. That, in and of itself, might not be a bad thing if they were in a polyamorous relationship, but it doesn't seem that it was the case. Just because she confessed doesn't put her actions above-board. less

My ex bf would cheat on me all the time. (we lived in different towns and never lived together). I suspected it, but didn't find out for a very long time. He never would admit it, but I met more than one woman who told me they were sleeping together. These women had no reason to lie to me.

Anyway, I ended up starting to date other people (no real relationships, just casual dating) and I DID sleep with a few guys. The ex finds out because I admitted it to him, and he always reminded me what a "slut" I was in his eyes. Yet, he continued to come around and want to sleep w/ me. He claimed he loved me like no one else. In the meantime, he continued to DENY ever cheating.

I say he was very mentally/emotionally abusive, and am in therapy over it. What is your opinion on the subject? less
