<human>: Can you give me a shortened version of the text?

My boyfriend is 31. I am 22. We have been dating for ~1 year and still, he refuses to stop talking about his ex. He lived in NJ for ~3 years and dated a super girly girl. He broke up with her and moved back to MN--2 years ago--which is where we met.

At first, I didn't really care. I'm not the jealous type, and I figured it would stop soon enough and maybe he was just venting or something. He would occasionally complain about how obnoxious or dramatic she is/was and anecdotes from when they dated. I usually just nod and don't encourage it.

He loves watching ANYTHING about NJ. Parodies, TV shows, movies, etc. Every time he does, he has to bring up his ex and all of her antics. I've told him before I'm tired of hearing it and I want him to talk about her as little as possible. I don't think he's taking me seriously though, because the behavior continues.

I don't want to blow up at him, although I'm very close to doing so. How can I tell him in a nice but firm way to knock it the fuck off?
<bot>: My boyfriend continues to talk about his ex after ~2 years even though I've told him it's annoying. I'm at a loss of what to do about it.
