yeah asshole i saw the typing mistake after i posted this im too damn lazy to go back and change
I find it funny that you'd be too lazy to edit an easily edited title, but will go out of your way to verbalise your displeasure to a complete strangers derailed post AND tell him you were too lazy to do the simpler task. Probably not as nice a guy as you think you are... just saying.
On topic, you have 3 options...
A): forget about her because she will probably do the same to you and move on.
B): tell her what you think of him, not as an excuse to get her back, but to point out her foolishness and then move on.
C): beat his ass because he sounds like he needs to be put in line, then move on.
Whatever choice you make, move on. Otherwise you'll just become bitter over it which could sour other relationships (your friends might not want to hear you on about her, you might carry grudges which can get you into trouble or cause you more misery etc... case by case really).
If she's suddenly illuminated to the error of her ways, don't be too hasty to take her back... chances are she didn't learn a thing.
