Ex-Boyfriend dumped me--why is he upset that I'm doing fine?

Me and my boy friend got in a fight a week ago and he broke up with me during the argument. We're both freshmen in college and his parents told him he can't date until he graduates college. His parents called me, my parents and said a bunch of rude things. I got quite mad at their parents and I think they are really rude and low. This topic came up a week ago and I told him that what they did to me and my family was really "rude and ridiculous". He flipped out and said I crossed the line by talking sh*t about his parents to him. I asked him if he really doesn't think that how his parents reacted was wrong and he said "they were just a bit harsh but they were not rude or ridiculous as you say they are". He broke it off, I accepted it that it was my fault apologized and moved on. I went out the whole week met people and so on. He contacted me right after the break up asking how I was feeling etc etc then after 3 days he goes "it's so hard to move on to me while I talk to you so I don't think we should talk until I recover from this break up". I was always bright when I talked to him even after the break up and went "okay (: hope you feel better soon :( ". After that he keeps on uploading depressing status's and told his friend that "We broke up because she wants me to put her first, even before my family. And that, I cannot do. I heard she's doing fine after the break up I can't believe it's me that's going through all of this suffering.. wt*".. During our relationship he was the nicest guy ever, did everything for me, and we went along perfectly. He told me "I hope you move on.. I really don't want you to suffer.. I'm sorry.. I pray that you get better soon" right after the break up. Now that he see's I'm actually doing fine, he's all like "apparently she's doing fine.. what's wrong with me? it's only me… what the heck". He honestly is kind of a mama boy though he does not admit it. But why is he acting like this? I still kind of feel for him, but I think he is being really selfish at this point. Saying that we broke up because "She wants me to put her before my family", when that was not the case, and saying things like "apparently she's doing fine. and I'm going through this suffering." playing the victim when he's the one who dumped me. Any opinions? should I just keep acting like I'm doing fine and stuff?
