Hey folks. I recently met a girl and we hit it off. However, we're both in relationships, and we're colleagues in the sense that we work for the same company, albeit in different cities and under different direct managers.

I feel like there could be something there, but because of the work and relationship issues I don't want to come on too strong. In a couple months' time I'm going to make an excuse to go to the city she lives in, and invite her to a friend's party. See if we hit it off further.

From now until then: how do I keep her engaged in conversation to such an extent that an invite to a house party in 2 or 3 months won't see untoward, unexpected, creepy, etc? There's only so much to talk about that's work-related, since we work in different places, but I don't want to come off as some douche who is trying to step out on his woman for a fling with a coworker. Y'know? Any advice?
