you gotta work on being less jealous & more trusting
unless you've actually seen them together or have a rly good reason to think that she cheated on you or something
that's part of being independent too - having your own friends. not everything has to be centered around your relationship
as far as irl friends go, just talk to them about anything but her. i mean. it just makes it worse right?
clear things up with them about you and her splitting and then get on with it.
basically, breaking up is always ****ty - especially after a huge fight because it just seems like you could've worked things out if you had enough time and patience. but it happened so figure out what's next for you.
be analytical. like a guy
