<human>: First post, seeking advice (sorry in advance if lengthy)! I've been dating my SO For about 3 years now, let's call him Max a 23 year old male. I a (21 year old female) am confused and don't know what the hell to do. 

Lately I'm not sure if I'm really happy anymore and he's been talking to this girl who I absolutely HATE for awhile now and they decided to go hang out today at the movies. They're friends of course and she has a boyfriend. The reason I detest her is b/c when him and I broke up awhile back, he attempted to get nudes of her and he even told me that as soon as him and I broke up, her attitude towards him changed into flirty. 

Of course I was pissed off b/c everytime I ask him to go on a one on one date w/me to the movies, we always go with a group of friends, so this really bothered me. I used to talk to someone he hated as well, but he found out so I stopped. I never hung out with the person he hated though. He has done a lot to change for me, he deals with anger issues and his jealousy has subsided quite a bit. I'm not sure whether I should let this bother me to the point where I should break it off or not.

Give me a shortened version of the text
