I had a two year love affair with a co-worker once. Good thing, we worked, at different locations.

One night, we went out with some friends. Ugh!! Something happened, and I ended things, right then and there.

Didn't have to face him, all too often, with work, just at monthly managers meetings, etc.

He moved away, after I'd stopped working for that company and life just carried on.

How much, do you have to deal with this guy, on a day to day basis? Do you work in different parts of the building? Or do your work paths cross more often, than that?
