No guy you meet in the places you meet guys WANTS a serious relationship. You want them to want it because that's what you're looking for. Why don't you try the personals.
"Wanted - serious relationship with twenty-something male" If half kidding, but half not. You have an agenda - you want a serious relationship - and your agenda is in direct conflict with the agendas of every guy you meet - they DON'T want a serious relationship. You've heard that here for ages and yet you continue to convince yourself that 'this guy could be the one' from the second date. He isn't, ok? He isn't the one you're looking for.
