Well this has certainly happened to me, but only half of it is true (no pairing involved) and it's not an RPG.
Witcher 1 is the example here. Let's say you don't know nothing about the backstory of the game (didn't read books). In chapter one you meet Shani that becomes a love interest throughout the game. Then in Chapter 2 Triss pop's up and confuses the hell out of me because I have no idea which to choose so I go with Triss because apparently it's "canon" (I read up on it) so I decided to stick to that. It was rather awkward to be perfectly honest.
Not really answers the vote, but I thought I would share it where you are on a path with someone then someone else gets thrown into the mix and "forced" onto you so to speak.
