Actually, it's really not. I'm applying for new jobs because I've grown sick (and, quite frankly, outgrown) my current job.
I'm a once and future network/email administrator but have been working in software support for just about a year now. It's time to move back into my comfort zone.
Now, I just have to get one of these hiring managers to agree with me about that.
I guess it depends on exactly what you want with the person and who you want to be right now.
I say "who you want to be" because after doing the long term relationship thing for awhile (the last one lasting 5 years) I decided that I was being stupid and selfishly wasting someone's time (and my own) by trying to be in serious relationships at this stage in my life.
Since then I've been a slut. It's pretty much the first thing I tell someone when I meet them (if I'm remotely interested) and more often than not, ends up creating a closer bond because of the honesty. Out of that I've had some fantastic non-monogamous relationships that have turned into great friendships.
So, if you find this person attractive and they can handle the idea, maybe you should consider seeing them in an open relationship?
Otherwise, you run the risk of leading them on - they're always going to hold hope out for you and every sappy look you give them will be an open door in their eyes.
Communicate explicitly and often. Life is too short for head games.
Or hear it and don't care to believe it.
Or, perhaps most often, the heart overrides the brain and everything that has been heard is lost.
All you can do is keep dancing.
