What do bạn do if the guy bạn like has a girlfirend. Also what do bạn do if bạn know that he knows bạn like him.

just relax
thsi has happnd to me
he knew i liked him but we wer till really good mates =)

Yeah, definatly get to know him better. But don't get in the way of the relationship with him and his girlfriend, as this can cause fights.

I'd say be friends. Maybe one ngày it can go further, but 'just friends' till then.
