Answer I'd say a face to face confrontation is needed here. No one likes being lied to so if that person who is doing the lying and isn't man or woman enough to admit it, confront them face to face and tell them you think or know they are lying. See their comments after you face them down.
The best, and in my opinion the only right way to do it, is to tell your girlfriend you need to talk and say it to her face. That way, you aren't a loser. Or a wimp.
