Am I wrong for being upset over this?

If I am wrong for being upset over it. I will learn to get over it. But I feel like it’s wrong and it bothers me.

So, I’ve been with him for a little over a year and he broke up with his ex about two years ago. But he’s still like, I don’t know how to describe it. He wonders how her life is going and stuff like that, and he brings her up more then I’d like him to. Like “oh I remember how she used to do this” stuff like that kinda.

Today she got kicked out of his old school, and he was asking everyone about how she got kicked out and how he pityed her stuff like that (which is eh. But he pushed me off to text all his friends about it). And he added her back as a friend on

Facebook to see how her life is going.

Idk he just brings her up more then I think he should. At least 5 times a month.

Edit: I should add that I’ve told him I’m bothered by how much he mentions her and stuff, and he brushes it off.
