My fiance broke up with me and im sad but what hurts me the most is that he said really mean things to me...?

I can't forget all of the things he told me.. I went to the bar eith my fiend and i was dancing with guys and he was talking to girls but we don't even say hi or anything.. Is that normal.. Other few times i saw him too we even danced in the same dance floor but we don't even look at each other like if we never met.. Im so hurt fot that. We were together for 3 years. :( Is that normal?
