Thank you for your answer. You're right. Not because she hangs out a lot with another friend, does it mean she wants to ditch me..
I'm going on a trip for a few days and when I come back I'll talk to her about it, so it'll give me some time to think too.

I'm just scared that I won't have any friends, like for going out and when something bothers me. I don't wanna end up alone or something.
