Would you let your girlfriend move in with an ex?

It all comes down to how much you trust her. If she really cares about you she will re-think whats going on. the temptation it seems too great for me to be ok with it, but then again, i dont know this guy so idk how he is with her. my girlfriend puts me first and is willing to make sacrifices (like finding a different roommate in your situation) because she truely cares about my feelings. do you know the guy well? because if hes a total stranger to you, theres a serious trust issue that will occur between you two. If she has a history of cheating (not saying she does) but if she does then the game is over buddy. I couldn't imagine every night when i go to bed thinking of what could happen on the other end of the stick. Talk to her about your feelings, because this could get out of control for you and/or her if you dont.
