I'm a single guy who posted an ad online looking for a roommate and forgot to mention I was a guy.  A girl responded but said she was fine with living with a guy and she came to meet me and look at the place.  As soon as I opened the door I was struck with her beauty and as I got to know her I realized she's incredibly smart, funny, easy to talk to, witty and kind.  We've been living together for several months, get along great, hang out, talk all the time, etc. She had a long distance boyfriend but they just broke up. 

  
She mentioned in the past in a conversation she thought I was good looking, though maybe she was just being nice.  Then last night we were drinking and talking and she said she was really happy I was the guy who had this apartment. In another conversation she said if we both move to another city we have to live together. I don't think she's interested, though I'm not good at these things.  She is a few years younger too.  I'm wondering though, has anyone ever started dating someone that was just a roommate at first?  Could this ever work out?  Don't worry, I don't hit on her or let her know I really care for her and am attracted to her, the last thing I want is for her to feel uncomfortable living with me and to lose her as a roommate and friend.
<bot>: I'm a single guy who found a beautiful female roommate who is now single and I really care for her, but I don't want to mess things up or lose her so I'll probably never tell her.
