<human>: Here's the backstory. There's a girl that I work with that I've ended up becoming really interested in, but I'm not sure what I should do to break out of the "friend zone" with her. We've only known each other for a few months, and we've grown really close over the time that we've known one another. We have a ton in common, and whatever we don't we love debating about it (foundation of a healthy relationship, if you ask me). Holy hell, just last night I went over to her place and we played Crash Team Racing and Tetris Plus, watched a movie, and never had a dull or awkward moment. I look for the signs that she may be interested (unnecissary physical contact, playing with her hair, body language, etc.) and those signs tell me she's down. But the next moment, she'll snuggle up to me and say she's glad she has "such a good friend". So I just don't know what to think, and I think I may have fucked myself over by joking and telling her "you're too young for me" when we first met (she's 20, I'm 27.) I don't know what to do, and it's more sensitive of a situation than just "going for it". We do work together, after all. I'd prefer shit not getting awkward if I misread her. Any advice on the matter would be extremely appreciated. Thank you!

Can you condense the text into three sentences or less?
