Love isn't about sex but you still have to know how to satisfy. It's only nature we need sex and when sex is bad there's a problem.

I sense that you are very young but in no way you are immature. My idea of male immaturity is when there's a group of guys sticking close to each other then one says a bad joke with a tone of a retard then starts laughing like a monkey, the rest of the guys pick up the monkey laugh. You are right in your views, you suffer because people around you are immature but trust me you will get rewarded in a long run.

This girl that you like has definetly changed and it's hard for you to take it in. If she was someone wise she wouldn't have listened to some guys that she barely knows and she wouldn't have left her true friend behind. But it happened, be strong and more imortantly be wise... always think what would be the wisest thing to do

Don't even consider suicide... that is by far the stupidest thing anyone can do
