saying goodbye, was this the right decision? Options

[x_fatal_rose_x]

I had this boyfriend and he broke up with me but I still liked him a little...actually a LOT. I thought he still liked me because he was really friendly to me even afterwards and he still sort of acted as if he was my boyfriend... Then, we had this big formal dance, and I was just sort of making sure that he wasn't dancing with anyone else...(because I still liked him..) and he kept smiling at me even when I wasn't looking at him. He sort of looked as if he was going to ask me to dance but didn't have the courage to. At the end of the dance, I went to the other side of the room (and the last slow dance was playing) and I suddenly saw him holding this other girl's waist..and I was like "wtf" because he usually is way too shy to tell any girl his feelings. He's like a very shy guy (or so I thought) and then they started dancing. I was so sad, I was about to burst out crying but I didn't because I tried my hardest to keep it in. Then, he kept talking to me about her even online. Like he just kept saying "hey do you know I danced with ____? It was so cool...blah blah blah" Every word he said kept tearing me apart. He never danced with me...he never hugged me or did anything like that even when he was my b/f . So the next day, he IMmed me saying "hi" and I couldn't take it anymore so I said "Hey ____, I need to tell you something." And he said "What?" and I said, "I can't talk to you anymore. I don't know if you'll understand this now, but you might later if you think about it. Have a good life. Bye forever.." Then, I blocked him after I gave him a few minutes to say something but he didn't say anything. And I don't know if that was the best thing to do, but I'm trying to get over him by not talking to him at all. He's moving this summer, anyway and I said bye to him even before he moved. Was this a bad choice or a good one? I really want to forget about him.
