I did similiar things for a friend. Lent him money, got him out of jail, gave this fucker countless rides to places he had to go. If I ever mention if he could give me a few dollars he owed me, he got all cheap on me. Well I finally had enough of his BS and havent talked to him in a long time. Actually I think I better and happier person now. If things get any worse I suggest you have a talk to her or kick her out. Like the saying goes its never personal just business
