aww :[
first things first,
UNIVERSAL DATING RULE#1: NEVER Cheat!
and Rule #2: never cheat and break up with girlfriend for girl you cheated on her with!
the reason why you dont want to do that is because karma will always (and mark my words) ALWAYS, kick your a** in the end. like it did to you unfortunately.
but in the meantime, try to build your life back up. don't let her be your boss anymore. go back to your closet, and put on those daddy pants that once got you that jag and that bank job and then try to get your way out. It wont be hard but you can do it. once do you, then you can hit up that ex and holla. but don't do it while you have this crazy girl on your sh**. (no one likes baggage.)
but i am all for getting the ex back!
