Since last year I have improved a lot. I've gained 35 pounds of bone (I'm a teenager) and muscle and my body weight is at about 12-14%. Girls are usually pretty into me and I have had my share, I do well in school and I'm good at martial arts/ basketball / skiing.

My question is, well, to put it simply, why do I keep getting excluded from things? I usually hang around with the types of guys that get girls and get invited to parties and I have gotten invited to my fair share of parties too. Here's the main problem, though. Within my group of friends, there are a couple of guys that act really nice around me and crack jokes with me at school, but when parties roll around they try to make sure that I don't get invited to them.

It seems like those guys can say anything and everyone will agree with them, even make up some bullshit about something I didn't do and tell everyone and they'll all believe it and spread it around.

I figured you guys could help me out with solving this problem, and I can't really get a different group of friends because there are just so many kids my age that don't play call of duty all day and know what a party is and these are the guys that go to my school.

Is there some kind of "If you aren't getting X, you must improve yourself to Y or do Z" that I don't know about when it comes to teenage social life?
