First of all, why did he move here in the first place? Was it for a better life? If so, that tells you what kind of area he is from. Also, why is he running home to mommy(her suggestion of when is a red flag for that one)? If that's any indication, then he's a momma's boy which doesn't bode well for you with the whole "don't bring a gringo home" thing, you will be around his fam alot regardless of what he says or you think.
My suggestion is to find a real man who doesn't run when things get tough. It's time he grew a pair and stopped being a selfish prick who wants you to do what he wants instead of what's best for you (the sign of a REAL gentleman).
Also, jealousy could become a HUGE problem since you don't seem to spend too much time away from each other...can he not get another job there without the jackass boss? Can you say red flag...I can. He also lives down the hall from you, I doubt he has any trust whatsoever.
The friend thing is just an excuse, if you find a real reason, move...otherwise, don't waste your time.
