Most Helpful Guy
This comes up on gag fairly often. I really seriously can't figure out what's wrong with someone having a picture of an ex. I can usually understand people who think differently than me, but on this issue I just can't figure it out. What's the big deal? So he has a picture of an ex. So what? His ex was part of his life and pictures are a good way to remember the past. I just don't see why anyone would want to throw away pictures that were part of their life.
So the answer is no, don't bring it up. Yes, you are over-reacting.
