" Don't hate the player, hate the game... "

A few days ago my boy friend and I broke up. I did have feelings for him and I was in fact hurt when he broke up with me.. It's alright I guess, nothing too serious.. But his sister is also my friend and she told me the only reason he went out with me again was because he was bored.. Now thats pisses me off. Urg. And then this nasty chick whose friends with his sister was saying how I shouldn't be playing him. I didn't play him.. She thinks I did because we broke up soo many times.. I want to talk to her about this but I don't know how I'd word it... Advise please.... -Katie
