But didn't now they were going out an when I asked if he was datin anyone he said no. At the same time he was flirting with friend 2. But then i ended that relationship an since then we been only friends. He then preceded to break up with friend 1. In the end of july. And stopped flirtin with friend 3 about july 4th. Then started dating friend 2 on july 28. He still denies any relationship with friend 1 and flirting with friend 3. But now friend 2 isn't talkin to him and yes he is a player.
