<human>: I'm an 18 year old male, I met my friend a few months ago, 19 year old female, at the beginning of college. We've slept together a few times, spur of the moment type situations, and we've never wanted to take it to any direction that's too serious. The other day, I mentioned an idea I had that we might want to date, but after we discussed it, we decided that it was best if we don't date. The next few days afters she's acting really sad, and crying, being very depressed and generally being closed off to me. She's made it obvious that she wants us to date, but seeing as she's the closest friend I have, I really think it's a bad idea. How do I take things back to normal, before I even brought it up?

Can you condense the text into a few key points?
<bot>: My best friend wants me to date her, but I don't think it's a good idea, and now she's very depressed. How do I fix this?
