When I started dating my boyfriend, I knew he had lots of girlfriends before me. I also knew he was known for cheating. I kept thinking "He won't do that to me", "He changed", and when my friends would warn me about him I would say "He isn't like that any more." then I would find out that he slept over at some girl's place, and I was fucking angry. So, when i found myself with a cute boy, who wanted to mess around a little bit, I took the opportunity. A little bit into the future, I broke up with my cheating boyfriend, who I cheated on.
