If you do have a less-than-perfect break-up and you still have to work together, yeah, things'll get ugly until either of you change jobs. That's a risk, but one I'd be willing to take.

You might still be in the lovey-dovey phase of your relationship too much, and it depends on what kind of person she is, but maybe you could discuss actually picking the night shift to avoid spending too much time together (people who think this isn't a bad thing have either never had a relationship or have just started one).

Though, when I think about it, that could probably easily be an invitation to a big fight. Not all of the womens like to look at their relationships in such a pragmatic way. Choose your words carefully.
