My close friend from highschool. I used to cherish her alot and I once considered her as a best friend. But she didn't feel the same way. She recently shared how she never expected us to be so close but we're only this close because I constantly reached out and was a good friend. She constantly treats me like I'm optional and ignores me , even when I'm going through a hard time. Her excuse is always that she has a lot on her plate and this and that but I know she doesn't care that much about me . Problem is she's the only close friend that I've been so open with and I have problems establishing and maintaining relationships so she's the only one I can rely on while she can always treat me like an option. I'm trying to put some distance and look out for myself but I know it's not permanent, there's no perfect solution that can help me at this point
