I'm sleeping with her boyfriend... what do I do?!
I am pretty sure the guy I am sleeping with (casually on and off for years now) has a girlfriend. It even looks like they are serious and have been dating for a couple years. I definitely plan on telling him I can't have sex with him anymore... but I am torn on wether or not I tell his girlfriend. I have tried to put myself in her position and see if I would or wouldn't want to know... or if I have the right to tell her... HELP
