What do you think, is it worth it?

So this girl that I really like decided she just wanted to be friends, after talking for like 6 months and it sucks but she still wants us to be close. I have a feeling that she is eying someone else now but the other day she told me she misses me and how close we were. This really threw me off but her statuses on a social site and stuff say “can’t you see I really want you.” and stuff like that and I honestly doubt it’s about me. I gonna do something that never seems to work but I’m gonna spill my guts to her hoping this will sway her but I don’t know… We’ve been through so much together, I lost two best friends because of her, one of them who was trying to date her first but then I kind of stole her from him but I thought it was worth it because she’s changed my life and she tells me that I’ve changed her’s and I can’t see myself with anyone else but her. I can honestly say I need her but do you think she’s really worth it? I’m just scared of getting turned down.
