I cant deal with it anymore?

You say you want to leave him and you've told him, but he doesn't let you. You said y'all "make love" then you leave. Are you physically goiing to him, in other words, driving or catching cabs to his place? If you're lending him money and he's that much older than you, and he has a job where he should be earning a good amount of money, that is a big red flag. Are you sure that his is job or is it possible he told you that to attract you to him? Maybe a subtle promise to make you a model? Is he physically abusive to you? Is the method he uses to keep you coming back, going against what you really want, mostly psychological? If he's not physically abusive and he's never threatened to kill you if you leave him, then the answer is easy...just leave him. If he has threatened you, then you have to go to the police and report that and get a restraining order. You either really want to not be involved with him or not. Does he know where you live? What kind of "support system" , i.e. friends, relatives, do you have? If you think he's capable of hurting you, then you need to tell them and let them know that you are about to end the relationship. If he's not going to hurt you and just wants to hang on to you, then just end it, Change your cell phone number, that can cost about $20.00, block his number if you have a landline number. Tell him, in no uncertain terms, that you do not want to be involved with him anymore, and you also want him to repay you the money you've lent him. But I wouldn't make a big stink about that, because he may use it to string you along some more. It sounds like he is clearly taking advantage of you. You're probably very pretty but he has some issues. Don't look at the fact that he sleeps with you as any evidence that there is love there. If he can be with someone that has told him they aren't happy with him, he clearly has issues. And, if you are around him again and he tells you to go away, I would do just that, go away, tell him he's right, you should go away, and then stay away. Good luck.
