So should I flirt with him or just let him be?

OK weve been friends this whole year, really good friends. At the begging of the year it was more like I was picking on him calling him names just to get on his nerves cuz at the time I didnt like him, and later on as the year progressed, i kinda remember he was like always asking me who I liked or something but I didnt think much of it because..well I didnt like him. Until about the last quarter of the year we started to flirt alot like online, myspace and at school. But now im starting to find that this freshmen girl realy likes him and is always flirting with him and talking to him on msn, myspace and on the phone. And he doesent talk to me like he use to, but on the last day of school he added me to his top friends list on myspace, but im after that other girl and i dont know I always heard and could tell that he likes to flirt with girls so do you think i should just let him be or should i go for him?

Casually ask him if he likes the other girl see what he says. If you really like him then yeah you should do something about it, otherwise no. If your just missing teasing him and playing with him then dont do anything.

Reply:I think its always better to try it out and see what happens. So just flirt with him and see how it goes.

Reply:just keep doing what you're doing(talking to him) and if he likes you more than that freshman girl... he'll go back to how it was
Reply:if you want to, go for him!
