Not just to go on a date but to become officially boyfriend and girlfriend? Would you want the girl to plan something nice like dinner and a movie? Going out to get drinks or something? Or something casual like being asked while your just relaxing together?
The thing is, I would never ask a guy out but we dated and I broke up with him but we've gotten even closer then we were before. He's not going to ask me out because I already broke up with him.
