Girls, should I just give up on him? (guys can answer too)?

I think you should talk with him.Comunication is the best way to solve this problem.In my oppinion he has some problems I guess,but if he has not and he's lying you.Better give up on him.But if he has problems and all that stuff I say to be next to him and cheer him up.I wish you good luck and hope everything will be allright!
