While I know that you don't want to hear that he said that just to get you back, or in bed, or something of that nature, that's what I'm going to tell you. He thinks that he's too hot to handle, so in order to win your heart over he tells you that he loves you with his predicted outcome being that you'd never turn down such a prize man as him. You, thinking rationally, forced reality to come slamming in on him. He cried because he realized that people are going to find out that he's not Mr. Hot Shit anymore now that he's been turned down. He's going to whine and cry and bitch about it until some little tramp comes along feeling sorry for him and gives him some sympathy head, then he'll be completely over you and right back on his previously high flying ego trip.
Good work faraway, it's about time. Now go for what you really want.
