<human>: Hey, /r/relationships, hopefully you guys can help me out.

There's a girl that I've known since we were much younger and in the last few years, we joined a mutual friend group and have become really good friends. I've come to realize how amazing of a person she is, to the point that I would really, REALLY like to be in a relationship with her.

Unfortunately, I have no idea what to do. There are times when it feels like a relationship could be great for both of us, and that she's interested, and there are times when it feels the opposite. Even worse, I don't want to ruin what we already have. I value the friendship we already have, but want to take it further. I also have no idea how this could affect the group of friends we're in.

I really want to get rid of the "what-if" factor, any ideas on what I should do/ how I should approach this?

Give me a shortened version of the text
<bot>: I like a girl a lot, but don't want to make a good friendship (and group of friends) weird. How should I try to take things further with her?
