Okay, so my best friend for 7 years is a huge player. He gets a different girl every week, and for some reason they all know that but keep coming back to him. He goes to a different school than me, and wants me to introduce him to all the girls at my school. Maybe it's jealousy, I don't know, but he's told me about 10 times in the last year,"Hey dude, let's go to a movie and invite some of the girls at your school." But I never want to, because I know what's going to happen. Last year at a hotel party for New Year's there were these two girls who were there and we introduced ourselves. One of them was single, the other had a boyfriend so both me and him decided to compete against each other as friends for the single one. Well, about an hour later I fell asleep, because I got bored and it was late and I wake up and I see my friend making out with the non-single one, which kind of pissed me off... I asked where the single one was and they said she had to leave. Now he got a Facebook and is trying to add the girls from my school to talk to them, but I don't know how to tell him to stop without sounding like a cockblocker. Do I have the right to do this? From this post he kind of sounds like a prick but honestly he is my best friend. One time at school I got into a huge fight with some kid and the kid got his friends to back him up so my best friend backed me up. We have so many moments together that I know he is my best friend, so don't convince me otherwise.
