Sounds like you're starting to see the reality of what this guy is about . . . and deciding he's not who you want to be with. That's a great move forward. It sounds like he's done everything he can think of to make it clear that he's there basically to use and abuse you. Ending this would be a good move. Don't make it complicated. Don't worry about where he is going to live when you tell him to leave. He probably needs to spend some time in shelters to understand that he has to provide for himself. Most likely he will look for another goodhearted woman to take him on board. Eventually, he'll probably find someone. Make it a point to not know about his life. Otherwise, you'll stay involved and cling to the fantasy that he may change. He won't.

Once he's gone, the most likely thing that will happen is that you'll end up in another exploitative/abusive situation. That's just a statistical fact. But it doesn't have to be your destiny, if you'll do what it takes to protect yourself. Understand that men like him can spot a soft touch like you from a mile away. It's not necessarily that you go looking for these guys. They find you. (I've been there. One guy even told me that, in a nightclub crowed with people, he spotted me as "the weak one" in the herd.) As someone above said, check out a man's value system before getting involved. We are capable of "falling in love" with a person for a bunch of reasons that have nothing to do with whether this is someone we can build a decent life with. Hard as it is, you have to learn to ignore that "love" that you feel. For you, it's a totally unreliable motivation. You're capable of loving a decent person, but you won't get a chance to do that if you let losers waste your time. Your life . . . your time . . . is far too precious.
