My friend and I from school are like the best of friends at school but sometimes she ditches me. Like completely runs off, usually to her sisters class but it still s**** that’s she doesn’t even tell me or ask if I want to come with her. then at training which we do 5 times a week together it’s like we don’t really know each other that well. Sometime she like “jokey” insults me but it feels real. I don’t know if she’s just acting like she’s my friend because she doesn’t know anyone or if that’s just the way she is. Advise would be great.
