I can't even call her my friend but then I feel like its the only thing to describe our relationship because we're in the same friend group. Anyway, we've gone to completly different universities - hours away from each other. It never bothered me because we weren't close so its not like Im upset about it and I know the feeling is mutual. However I can't help but worry about her. Since the start of sixthform - year 12- she's been getting more confident, which is totally fine. But then towards the end of year 13, she's been too confident to the point where people have thought of her as arrogant and cocky as she constantly throws herself at boys. I feel bad for saying this but she does act like a pick me and sometimes a slut. I feel bad for calling her that because it is a very extreme and cruel thing to say but she just literally is one.
Anyway, we were never that close and she's always been nice to me so I never was mean to her or anything like that. But as we started university, shes already been intimate with a couple of guys and slept with one of them and she didn't use a condom, a morning after pill and her period is late. She keeps brushing it off as if its not deep and that everything will be fine. She's always been very relaxed but almost to the point where its frustrating because she doesn't take anything seriously.
I don't know whether shes pregnant and I hope she's not. As I said before, we aren't that close - in fact, we haven't even spoken for months and the only times I here about her are from my friends who are closer to her. I'm not sure how to handle the information because I can't help but worry for her but I also feel like its not my place to talk
