My bf has been acting funny?!?

I would just give him some space , he may have something else on his mind that he's not ready to disclose yet. When my husband acts like that I leave him alone and he'll usually tell me whats on his mind, usually a work issue or something silly to me but serious to him. I'm sure it's not a big deal and he loves you very much. Men and women deal with things differently. Good luck.
