How many chances should you give your girlfriend?

In my first marriage we both cheated on each other and we were both so devastated we got divorced. I vowed that I would work harder in my next relationship if that happened. Well my next relationship came along and she cheated on me once ,so we went to counseling. I warned her that my patience was not infinite. She cheated several times after that with the same guy ( her x boy friend). I broke the relationship off because among other things she wanted to get pregnant and I didn't want to be raising a child that may not be mine. Bottom line from these experiences: work very very hard to make you relationship work including getting rid of your anger and if they continue to cheat break it off decisively no matter how much begging & whining they do. You have to respect yourself first and that includes doing everything to make it work including counseling. If they continue to cheat break it off. If you are a man you can never be sure it's your baby. If you are a Womyn how'd you like to be living with the same guy when your pregnant? A Womyn needs to be feelling supported during her pregnancy by some one she trusts. Break it off like you were ripping off a band-aid quickly and don't look back. Get a restraining order if you need to.
