Cheaters are lowlifes...unless you are a lowlife, dump the broad.

She cheated on You 3 times ????

Dude the question You should be asking your self is are You a sucker for punishment? by taking her back after She slept with Tom, Dyck and Harry she know thinks she can just do it when ever and you'll be there this chick has some major control issues that start with her vagina and end with you wondering whats going on pull the rip cord on that parachute dude this relationship is over do we need to spell it out for you the writing is on the wall this chick has zero respect for you taking her back.

after the second time you should have never dated her again. Im sorry but you did that to yourself, If she cheats on your MORE then once then chances are she would do it again.

Time for her to walk the plank....
