This guy friend and I chat a lot and have done so for the last few months. We flirt a little too...he always says 'we have to have a dinner, movie, do a trip'. Anyhow, seems we are now planning a short trip, just a weekend (as he has moved from the US a year ago and is still getting to know the place). He is a friend of mutual friends and is a nice guy. Do you think he is interested in me? Can a guy do a trip with a girl who is only a friend?
