<human>: I met him about 3 weeks and then became exclusive a week after meeting him. I knew he had problems with his ex and I will even say still hung up over his ex. They broke up about 3 months ago. 

He's trying to work things out with her even though she's just a lost cause. She used him and cheated on her boyfriend with him (so I guess this chick had 2 boyfriends at the same time.). By what he has told me, it doesn't seem like she wants to work anything out with him. This has become such an issue that I had to tell him straight up she's only playing him....which caused him to have a breakdown.

I have pointed out to him that this relationship will not work if he keeps trying to work things out with him. So essentially I gave him an ultimatum.

He has tried to meet up with her to talk, but every time she makes these stupid, lame excuses to not come. They finally met up today, but I guess didn't go as expected and will meet up ANOTHER time to talk AGAIN. He didn't even tell her that he needs to let her go. I'm just so frustrated over that. I don't feel that it's fair to me that he's gonna keep trying to fix things with her when she obviously doesn't wanna fix things.

So am I in the wrong here or are my feelings justified? What should I do?

Give me a shortened version of the text
