I'm so angry, excited, happy right now....I have so much mix emotions....Please help me....

For those who know my story.....Aaron was there.....

Gosh....he was in the dance party from the class with the other girl....he said he's dating her for 6 months. This new gf is the best friend of the girl that he dated just after me....and there it is....all three girls are there....me, the girl that he dated after me and the new one!

....It made me sick to my stomach and I acted completely weird and said thing that I shouldn't have, but I don't even care....I even think why I didn't say more....like when he introduced me to his new gf, I told her that "oh, I'm the EX"....and she made a comment that he has to date so many girls till he find the one....such a thing....I said nothing at that time and he told her right in front of me....I don't think she understood....I can't believe I didn't say anything....I want to email him and tell him that....

later on he told me that he didn't like the whole thing and it was so awkward.....and he said...I don't like what you are telling me....because I told him that he's a player....I said....I don't say that you like it....I don't care....

he was totally pissed!

I can't believe I was going so much out of my way.....for what?
I think I'm still pissed at myself that I went out with him in the first place and hurt myself....then I haven't had any relationship after him while he had two relationships....

I think I'm so happy that I'm moving out from this city.....It was end of era!

But at the end, I'm happy that I don't have such a jerk in my life....who can trust such a person....he will find somebody else and move on so quickly....

Not sure if I should email him?

Just wanted to clarify with him that I did understand what his girlfriend told me....I just didn't want to make any comment....I hate that he said right in front of me that I didn't understand it.....not sure why I said nothing....
Should I email him? Now that I went this much far?

thanks
