One of my best friends at school has recently started making me very uncomfortable. She hasn't done anything different, I'm just uncomfortable by it. I've been really stiff for the last couple of weeks and I feel like she's noticing that I'm acting different. I don't want to lose the friendship but I am extremely uncomfortable with her invasions of personal space. I also feel like I don't really have the right to tell her to stop because she hasn't done anything. One of my other friends also told me that she has a crush on me, which makes me uncomfortable as well, but I don't think that's the cause of my change in behavior, as I learned about the crush after I started feeling uncomfortable. What should I do? Pls take my age into account with the situation (14). Thanks.
