My dad cheated on my mom thrice and they separated six months back,my ex with whom i was in a relationship for four years since since junior high cheated on me while working a night at the club(strip) she had promised she would never do lap dances or even be intimate with guys there etc if i allowed her to work(which i did) only because she enjoyed dancing and it meant extra cash for college which was quite an important factor a year ago.
