There's a saying about throwing good money after bad. This example is the definitive definition of that. Take the words of the Amityville horror and "GET OUT"..... There is no good thing that will happen from here on out. Take bodegahwy's advice and realize that you haven't even begun to think of all the ways he's going to continue screwing you. In philosophy this is a simple finite / infinite problem. You have a finite definable amount of time and money into this now. Go forward with this penny wise / pound foolish LL and you'll have an infinite more amount of expenses and/ or lessons..... I don't know about you but my supply of both is definitely finite..
