I dont know what to do, Please help

I am 17, I have never really been on the dating scene. I have had a few girlfriends but nothing really serious.

My best friend was dating a girl, hes one of them guys that are rude to girls(example he told his girl to come over, she hasnt before and said you have to talk to my mom and said its over im not doing that and kinda cussed her out over the next couple days if she would text him he would say like loose my number bitch) so i told him let me text her, this was two weeks ago. me and her hit it off and went on a date. yesterday we went to our school basketball game and i was with her and everything was fine and good. We texted after that night like any other night. then all of a sudden today we dont text and she takes me off her top 8 on myspace and puts my bestfriend back on there. He just told me that they started talking again.

I dont get why girls go for guys that our rude to them, i am incapable of being like that

is this guy really my friend?

im about to just call it quits with girls and start doing drugs again

 

We're not all into the bad boy thing. I'm sure things will work itself out.
