I Think He Lost My House

Well, if you have been following along, you probably know that I signed over my half of the house to him because he was really bothering me, trying to get me to pay on HIS credit cards so I just gave him what he wanted. I gave him "our" house, the one that I picked out. It's been years now that we have been together and he finally told me that he was moving in with his Other Woman. He wanted me to take over the house, but he wanted like 5 thousand dollars, on top of that, for me to pay the back 2 years of taxes he owed AND the 3 thousand he was behind on the payments. I just am not able to do that, nor do I want to bail him out once AGAIN. He told me that he wanted to keep the house because he thought I was going to go back to him again, but since I didn't, he moved in with her and is no longer interested in keeping it. My grown son was going to step in and take over but being as young as he is, just starting out and all, I doubt that anything happens. I know the man who bought and financed the house for us, but my ex told him that I was the one who walked out....basically true, but he didn't bother telling him WHY nor that he cheated on me with several women and that he wasn't willing to make things work. He always makes me look bad, but at this point, I really don't care. I know the truth, he does too, but he just doesn't want to make himself look bad. All in all, I guess that house was really never meant to be "ours" because right from the moment we moved in it, he was starting up his old ways and all I had was suffering from his games and other women.
Sometimes you don't want to let go of something that truely meant something to you, but then again, there are times that you just HAVE to.
