So I sometimes hangout with my ex, we dated for a a year a while back and she occasionally wants to see me or hangout which I don't mind. She lets me fuck with no strings attached and it's convenient.

Lately though, I don't know if she's trying to make me jealous, but she constantly talks to me about other dudes like I'm supposed to be engaged in the conversation. "My co worker is so hot, or I just made out with this guy this weekend". I joke about it and act like I don't care but it's seriously annoying. I'll try to have a conversation about some dumb shit and she always manages to bring in the topic of guys hitting on her, or bullshit related to that.

Now, I've moved on, that's not the issue I promise. We could stop talking today and my life would be the same. But how do I tell her to shut the fuck up? We're really close and she tells me everything, but this is the shit you talk about w your girls. It's not worth the pussy cause it's annoying and seriously makes me think less of her. Why? Cause I realize me telling her about the girls I've gotten with since we broke up isn't going to benefit either of us. Why is she like this?
