My girlfriend is an admitted former serial cheater. She's been in therapy for four years for it. She was "better" with her last boyfriend, but still cheated on him at least 20 times over four years. Some were breaks, but sleeping with someone the day after a break and then getting back together counts in my book (ESP as he wasn't and didn't know. I was like, he wouldn't have gotten back with you if he knew). We are madly in love and just moved in, and she is so happy she isn't living a double life anymore. Says it's like being an alcoholic, once you are clean breaking the streak is something she doesn't want to do for herself, and she would never hurt me. But, she's been like this for over 20 years and was only faithful to one guy that whole time. Can a tiger change her stripes ladies?
