Overthinking... ugh

So my husband and I have been married for almost a year and we have a amazing relationship. But before we were together he got around ALOT and that weighs heavy in my mind a lot cause I overthink a lot of situations. I’ve accepted his past and don’t judge him for it at all or hold it against him.

Anyways tonight we were messing around and talking about how one of his buddies is a virgin and needs advice so we were helping him out to the best we could to ease his nerves.

Well my husband starts bringing up all these past girls that he’s been with and I start getting jealous ( even though they were awhile ago)

And he brings up this one girl who he knows I don’t like with a burning passion for multiple reasons( not just that they’ve had hooked up) And he starts taking about their hook up and her types of bras and everything and I start to get hurt cause I don’t know why he’s talking so much about his past hook ups.

And now I’m over thinking and thinking he wants to go back to that life style deep down inside.. or I think about a hypothetical situation between him and a girl and my head is spinning

And I’m angry at him for bringing everything up but also angry towards my self..

I’ve distanced my self from him for the night ( we’re doing long distance right now cause of his work) to calm my self down and get my mind right... but something isn’t sitting right and I don’t wanna cause a fight over nothing
