Hi so I could use some advice here, I'll start with a little back story.
 So about 8 months ago this new girl started at my work, and something just clicked in me. She's shy so it was rough-going getting to know her but eventually we started getting along and even doing the sort of playful teasing thing. At one point we exchanged numbers and here and there we text one another but not on a regular basis. She came out for the tail-end of my birthday shenanigans and there are times where I think she may actually be into me. Two weeks ago we had our staff Christmas party, we were all a little tipsy but not flat-out drunk. At one point she came up to me and called me attractive twice, but we were in front of other co-workers so I didn't say anything. Then after I got home she called me and we talked for about 30mins, about nothing really but it was definitely not something that happens very often. After that things seem to be different between us at work, like there's sort of a distance between us. I've always been apprehensive about asking her out because we do work together and if things go south it could be awkward and she is 22 years old and I'm 26, not that I'm really concious of my age but she might be. On an unrelated matter I may be leaving this job for another in the next two months or so. I'd really appreciate any advice on this matter that anyone would have, my friends tend to give me the same responses to this problem so I'm looking for outside perspectives.
-Thank you

it sounds like she is giving you mixed signals.  perhaps her teasing /flirting is an invitation for you to officially make the first move.  sure you do work together, but you can't let that stop you.  if things should happen to go bad, then you are both adults right?  you can move on without it getting too messy i hope.  but as far as not dating simply because of the work arrangements, there really shouldnt be a problem there at all.  as long as you aren't her boss or something.  besides, if you are going to be leaving the job, then what's the hold up?  get to it!  talk to her and see if she is as interested as she seems to be.  good luck!
