Its not a question its what you think about this.?

Okay me and my boyfriend Dustin have been on and off for a half a year. Were not together now but i like him and he likes me. But he always flirts with girls and im not even on his top on myspace and for id like to meet and heros im not even in it. Only this one girl is. And that was even when we were dating. He had pictures of girls naked and in there bras on his phone. So of course i cussed out the girls. And he likes my best friend now. But the good thing is she doesent like him. Ive cryed more than once every week for 4 months probally. He is such a player and i think he might be using me. When the problems started going is when we couldnt go on dates anymore. Dose that mean maybe he was using me?
