<human>: Can you succinctly summarize the text in 1-3 sentences?

Thank you for the help in advance.

I've been hanging out, and talking to this girl on Facebook since the summer; I think we are just friends, but it's really unclear since we never established what are relationship is early on. 

We are both in college, but go for walks and go to the library together every so often when we are on vacations since we live in the same town. I've actually known her and have been friends with her since 4th grade, but we really only started hanging out and talking regularly this summer when we met up at our towns summer festival. 

We don't flirt or anything on these hangouts, just catch up on how each other is doing and talk and things like that; I don't think she has have given signs that has shown she wanted to be more than friends, but am not 100% sure. We don't talk all the time on Facebook either, sometimes weeks can go by before we talk again. 

We haven't hung out in a couple months because of school, but we will be meeting up again in the next couple of weeks.

I just have feeling for her as friends, but since we have been hanging out for a while I'm worried I could be potentially leading her on even though we have not really talked about being anything more. Sometimes it feels as if there is unspoken tension between us. I just want to make sure I don't hurt her since I care about her, and her feelings a lot.
<bot>: Should I tell my female friend, that I've known for years but started hanging out with last summer, I only have feelings for her as a friend the next time we meet or let things continue as is?
