What does this mean?

I'm not saying he's over あなた but I think he was in a high denial every time he supposely hated her and called her a slut... I don't wanna be a heartbreaker but I think he've been in 愛 with her for awhile, he was just hoping that it wasn't true so he called her many names to try to get over her but in the end there was no such luck in that for him.

フェイスブック is a horrible place to judge others, あなた can never tell if they are together before it's official and their statuses says they are in a relationship... It's just a generally confusing place, I mean just because your status says dating doesn't mean あなた are.

I honestly don't think he is happy. I bet his insecurity and losing あなた has led him to find comfort in someone totally wrong for him, and that person is his ex.

Trust me dear, if a guy is foolish enough to do this after he let an エンジェル like あなた go, then あなた are better off without him. あなた should stop looking または caring about what his status says. If he can go out and have fun あなた should too, I mean why must あなた be the one who is upset and he is out there having fun?

あなた should get out there あなた know, meet people, make フレンズ and just have a blast. Because this guy was a small part of your life and he isn't right now, so あなた should reclaim that piece of your ハート, 心 あなた gave him, fix it back with yours and live your life the way あなた want it :)

Even if he claims to be happy and over you, as a guy I can say that will be just his ego talking. Truthfully, if he wants to seek comfort in his ex, then he has もっと見る issues to deal with rather than the fact that he ロスト you.
