Why does my boyfriend keep mentioning girls that want him?

Like it’s one thing if it’s a crazy story that has some purpose behind telling me

But it’s another if he just causally mentions that girls asked for his number or tell him they want him, or flirt with him.

I don’t know if he’s just trying to be honest with me or he likes when I get jealous (and I’m NOT a jealous person)?

Like telling me that stuff only makes me feel like crap and insecure...

Here was the convo

How do I start the conversation that I hate this??
