"You had a boyfriend", because is actually talking with a girl, or a girl-like anyway, "that looked like a girlfriend that i had in february", it's not important who was that girl, the fact is that she had a girlfriend. Otherwise, if you are in a club and you discover that the girl you like is lesbian, do this create you some problem? And the theory about the fact that is ex-girlfriend became a man has no sense, and the time-fact (neither one year is passed) is in contrast with an operation that has longer times. In the end, the question is very simple, and every man feared, even for one night, that the girl he's approaching has/had some surprise....
