i need to meet new people

I have had the same friends for a while now and a lot of them are changing. Like a girl that I'm best friends with is starting to hang out with this other girl 24\7 adn her personality is rubbing off on my friend. As for the rest of them they are all...

acting really fake and they always talk about people or make fun of people. Im really really mature for my age. I enjoy hanging out with my aunts and older cousins. I guess since Im above my friends age level I don't have that much in common with them anymore. O and I attract the weirdest people for friends that always end up stabbing me in the back! no joke! That's happened to me 4 times now. Basically I'm tired of hanging out with highschool girls and their ignorance, so my question is how do I meet really mature people? I need some really good tips because I attract some weird people as friends

This always happens - I remember in high school everyone changed so much its weird to watch especially when its people you're close to but unfortunately you cant do anything about it. I think you should join school groups and teams that interest you so you can meet people who like the same things.
