Going into my final year of school, about to turn 18. Was a very social and popular person until the typical story - I met a girl, LTR for 2.5 years, became a bitch for her, she left me and then I realized I was now fucked. I missed out on a lot of social life, and I realized now I did not have a social circle. I'm popular in school and cool with everyone but outside school I only ever hang out with 1 or 2 people, summer has been shit so far.

There is a group in my school, we hang out at lunch and have a laugh, sometimes if I hit one of them up we hang outside school, but most of the time not. Usually when I text one to say lets hang out they're either busy, or they agree but when I call them to meet up they're doing something else. It's been pissing me off. I want to be part of them cause I genuinely like them and it is also good cause they know hot girls, other cool guys etc so I can use that to my advantage --> but mainly because I like them and just want friends to hang with.

So I know to be part of a group, you must add value. How can I do this? I'm always down for whatever, got connects for different shit etc.

Thanks a lot in advance and be harsh if needed.
