That probably one of the best points against dating a co-worker. If you spend all of your time with them, you are going to grow tired of them quickly... . Home, work, car rides, bed.... you are going to want some personal time.I'm all for looking for love but good god, 8 hrs together and come home to the same flipping person is too much!
Sounds like someone has a crush on a co-worker. If you work at a small office, I'd say don't do it. Things will probably be great at first, but eventually it can be straining. If you really want to date that person and you think it will work, go find another job... loland just for the record.
-this is all hypothetical-
