he's just not that into you, to borrow a phrase. he's being passive-aggressive and playing games. when you leave, oh THEN he's interested. when you stay, you're too much trouble. if it's like that at the beginning, it's only going to get worse. i'd say find somebody who doesn't love booze so much. there's a problem here, you don't need it. he's looking for someone vulnerable, don't be that person.
