Ladies or Gents Talk me out of being stupid please!?

ok yahoo answers is like my new obsession its soo much fun! Anyhow i found my ex's profile on here and he asked a question 2 days ago it was "Why is it so hard to find a loyal girl?" I know it sounds soo immature of me but it brought me a small bit of happiness like karma has served him right! I was that loyal girl and the crazy he is talking about is who he left me for and now apparently he has found this new winner he is asking about. Anyhow i am so tempted to leave a bratty response he screwed me over so bad (emotionally/financially) and i was too young and naive and stupid back than to tell him what an he was to me. Its all in the past now and i have found happiness. So should i be immature and petty and leave a snarky remark? or please affirm that doing such will not make me feel better and that i just need to move on and leave him and his drama filled life in the past! Here is his ?btw a href="http://answers.yahoo.com/question/index;_ylt=AngFV2AGA8W3DGd96rRfEN7sy6IX;_ylv=3?qid=20100522090915AAt0juw"http://answers.yahoo.com/question/index;…/a
