Girl here. I have accidentally had some random fun while drunk a few times. Not more than like five times over the last four years and last time was for almost a year ago. It was no feelings involved, and I've told my fiancee every time because i don't like to have secrets for him and he has forgiven me each time and we've moved on.

Lately he has started whining about it every time I do something he doesn't like. Yesterday he literally called me a whore after I used his credit card to buy an lbd. I work in a kindergarten, and last week, I put on some makeup and nice clothes before going to work, and he accused me for fucking the dads while they pick up their kids. The list goes on.

Why does he do this, what is he trying to achieve and how do I make him stop?

I'm starting to think he's fucking someone behind my back and that he's using the flaws from my past to justify it. Does this make sense?

Picture unrelated, just some random inspo
