Interested in a co-worker.. What to do?

"Dear Housewife,

Ok I’m going to try and keep this fairly short but give you all the info because I’m really at a loss at the moment.

I started a new job about three months ago. Since I started I have liked this guy (he's 24, i'm 21) who works on reception and is a kind of odd job guy. I work on the next floor up. So although we work at the same place and for the same company, we don’t work in the same department and we don’t work closely together.

He is what most people would describe as kind of a geek is guess. He’s intelligent, funny, good looking, a bit of an awkward person sometimes and has even admitted to me that he lacks self confidence.

We have been flirting for months now. We’ve found out that we have loads in common from our sense of humour to music we like and tv we watch. I think we both make excuses to talk to each other about work stuff when we don’t really need to and we email each other about nothing really important just so that we can chat. In short I really really like him and I’m sure he likes me.
However, I don’t think either of us has the confidence to approach the other about taking this outside of work and getting to know each other better. I think he has made a few attempts at trying to work the conversation round to meeting up. Like once we were chatting and he said something about him being different outside of work and it was only when I mulled the conversation over a while later that I realised it could have been an opening.

We don’t really have any friends in common at work that can slip a few hints or anything like that and I would rather keep this out of the work gossip and just get to know each other and see how things go without anyone knowing.

The one person at work I have told is a girl who I work closely with, go to lunch with etc and I know she wouldn’t tell anyone else. I have thought about sending her in (so to speak) to drop a few hints etc but I don’t know if that will work.
I would really appreiciate any insight you have and any suggestions as to how to move this forward.

Many thanks!"
