Who's the crazy one ?

Real quick background for my question .... ok so my ex and I broke up , he has since had sexual relationship with at the time , my bestfriend. They amoung many other people, that were considered friends lied about it and kept it from me for months. I kept asking what was going on and nothing but lies . Til finally he cracked . Then he wanted to get back together and we worked on it for 3 weeks until he f@cked this girl from his old neighborhood. Aka the neighborhood hoe. I tried lieing about but I had 2 much evidence , so I left . The day after I left he moved in a homeless girl and her 2 kids, he f@cks her, and then decides that he did but now he dosen't want a relationship with her ,he now wants 2 start all over with me. So I told him that he needs 2 get rid of that thing and her 2 kids b4 I even consider anything with him. So the funny thing is that he doesn't wantb2 put any1 out on the street . My question is wtf is the crazy 1 ? ME ..... 4 making such a ' demand ' as he calls it...? Or ME 4 even considering 2 try this with him again ? We have been together 4 almost 15 years , no kids .
