You need to back it up!! First of all why are you living with someone so quickly after breaking up with the first guy? You seriously need to slow things down before you get yourself in another mess. Why did you and the first guy break up to begin with? Obviously there were problems in that relationship and you need to work those problems out before you dump this other guy--who to me sounds like a loser. If you really want an opinion that will help you, you need to get rid of BOTH guys and try to figure out what YOU want and need in life. You must be young because you act very impulsively, so you need to slow the sh** down!
