Doppleganger Problems

We like watching the TV show "Parenthood." It has started a lot of conversations as we examine where their conversations went wrong, what they maybe should've said, what we'd say in that situation, and how we'd handle the problems that come up. But I've had one rather large problem with the show - one of the actors is a dead ringer for an ex of mine, and that ex isn't a happy story.

Seeing Jason Ritter, who thankfully plays a medium role rather than a large one, when he has facial hair, is a haunting ghost of my past.

To add to my cognitive dissonance, the character he plays is real stand-up respectable character who is thoughtful and mature. And while the ex had moments of that, overall, the experience was the opposite. So seeing that look with those qualities is just weird to me.

Anyone else have doppleganger problems like that?
