i've been in the same situation. and the girl he found is uglier than me. like 4 srs. they look the EXACT same.
LOL the girl my ex found carries around a PANDA BACKPACK. it's dirty and she sits there and snuggles with it.
Jealousy's a bitch. I remember how pissed I was when my ex got engaged (he'd started dating the girl within a month after we broke up).
Anyway, not much you can do other than fume about it for a bit, then get over it.
And...now I want a panda backpack 0.o...wonder if there any in stores nearby....
(Note: I cannot be held accountable for what is typed while under the influence of fan-frickin-tastic margaritas).
popped in the face? HAHA wtf?
Srsly.
Then again, I AM kinda nerdy, so....that might have a lot to do with it. Hm. Bet the zoo sells 'em.....
My ex and I weren't even broken up an hour and he had a new girl. Hah. /:
You can't really do much about it, but accept it and move on. Hitting her won't help. :/
Go write a poem and gtfover it. Is this the same person you've been posting about for the last month or so?

Lawl my ex dumped me, told me still loved me for the next 3 days then by 4th day he had a new gf hated me and never wanted to talk to me again. Relationships are fun! x3
If you punch the chick, I'll back you up.
Remember April 20th, 2011 when we thought the world might end, when the PSN was down? These guys do. Reminisce those horrible days, the catastrophic events! The homeless men! ...And, is that water orange?
Jealousy is terrible, but calm down. You're not dating anymore, he can do whatever the hell he wants to. It's not this girl's fault your ex doesn't love you anymore, and from reading this it sounds like you don't even know anything about her. You just sound like some psychotic ex-girlfriend.
