You would think with him having no one he would make it work with you and settle down.
Im going to be honest.. but hes taking the piss out of you. I take it.. its your house and your worried him being homeless?
Do you have kids together?
I seriously would say you have one more chance or thats it. Its your life tho. But it sounds like hes using you or taking advantage of you.. what time will he get in?
