My ex fiancé and I still live together in what should be just be a "roommates" situation. He broke up with me 3 months ago, right before I went into the hospital... simply put he didn't want to be together anymore. After I got out of the hospital I came home started packing and he asked me to stay as a roommate that he hated to see me go. Since then he has lead me on with sweet words and affection and even coming to my room at night. Over the course of the last 3 months I have got to see how much of a liar he really is, how he is with money getting his car repo'ed and even not paying the rent on time... I know he is no good, yet I still find myself crying all the time over him and very depressed. I try to remind myself of the cheating and all the lies and all the other girls and it helps but I just can't seem to let go all the way... any advice of letting him go would be helpful, I have never been in a situation like this before!

Well let me ask you a question? How can you get over him when he's right there all the time?

You've got to move out. If you are going to move forward you have to put your life into drive and go. Right now your stuck in neutral. Your stuck in the same place with the same guy, who is getting what he wants at your expense and you get nothing in return. I dare say you even get less then nothing because you haven't been able to move forward with your life.

Don't start up with a bunch of excuses about rent money or you have no place to go, just move out so you can move forward.

... any advice of letting him go
Moving out would be a good first step!
