I have to admit, my mouth dropped when I read about all the money he expected, and got, from you. Then again, when I read about him denying all the arrangements the two of you made regarding buying a house.
It sounds to me like he is just looking for someone to mooch off of and at this point, you are that person. I'm not sure what kind of hold he has on you, but this man is not someone who is relationship material. He's only out for what he can get and has told you as much.
You deserve more than this, but you won't get it from this guy.
