Am I crazy? How mean are these texts ?

When I first started dating my boyfriend I’d talk about my past a lot and not bc I wasn’t over it but because my past revolved around a lot of relationships and that’s kind of all the memories I had. I know it was insensitive and dumb. I wouldn’t share too much but I’d talk about them and at the time I even failed to realize he’s seen these ex’s and knows of them. Just through our mutual friends or the community. We’re Indian so everyone knows of everyone or is familiar somewhat.

Anyways one day he told me it really bothered him and I stopped and learned from it and felt super bad but I realized he’d make spiteful comments to me randomly about people from my past or comments I’ve made and be like “oh u love these types of guys don’t you” one time he even found all their last names and texted me their first and last names randomly while arguing about something else. He would always bring up random things relating to them at the worst times and tell me I’m obsessed with my past and my ex’s and I’d always be confused because I never speak about them anymore but he does.

He’s going to a wedding and I asked whose and he told me a name which is my ex, and we were on ft so I’m like who is that and he claims I got excited and the girls name is short for a guy I talked too as well.

Look at this text and tell me if I am crazy or deserving of this?

I feel like I’ve changed and I made a mistake but why be so rude to me? And once he starts he goes down a rabbit hole of everything I’ve mentioned about my ex’s and reminds me how obsessed I am with them?
