<human>: Can you summarize the given text in a few sentences?

I used to like this girl, story about it is irrelevant. I chased her for quite some time but I finally realised that it just wasn't meant to be, it hurt and blah blah blah, but I feel as if im almost completely over it, The only thing holding me back is the fact that we are very very very close friends now and she relies on me to cheer her up and things like that. 

She likes talking to me and says I put her in a good mood and she's always laughing around me and keeps telling me I'm such a great friend. But I just can't talk to her without some feeling cropping up again sometimes.

 I want to sever this friendship but it's strong and I don't know how. If I can do this im sure I can get over it all. How do I let her down gently?
<bot>: Used to like this girl, don't anymore. now shes attached to our strong friendship and i don't know how to break it without hurting her.
