<human>: Okay so basically I live in an apartment with my best friend and a few other people who work around the city and it works out well. He's a decent guy and we've known each other for years - I know him from college and he had an 2/3 year on/off relationship with my other best friend.

Anyhow, recently he is behaving differently. He's always spending time with me and always wants to do things with me, and he's started a bit of flirty banter and teasing which I tend to brush off.

Some of his friends from another group came out to a bar with us the other night and we were all chatting in our separate groups and one of his friends pulled me aside and started asking questions, such as did I find my friend attractive, would I date him if I was single, what did I think of him etc etc. 

I REALLY do not see him like that. I had a crush on him years ago when I had gone through a bad break up but overall I don't see him in that way - was his friend's questioning something to be aware of? I'm not really sure what to do because I feel a bit uneasy but I don't want to bring it up and embarrass us both and make it awkward!

Can you give me the gist of the text in a nutshell?
<bot>: I think my roommate/best friend has a crush on me, I don't fancy him back and it's making me uncomfortable, oh and I'm taken.
