Am I wrong for feeling this way?

I've known my boyfriend at the time for 6 years. He was the my first everything!! We were two young teenagers in love but unfortunately we separated ways for some time and I dated my fair share of dudes after the break up. we got back together and of course I was curious if he got with anyone else or has slept with anyone else and he told me no every time and I honestly felt super guilty and told him what he wanted to know and he kept making comments and making me feel bad. Moving forward, we have been married for a year and now have a child together and he's now just telling me he dated multiple women and slept with someone else. I'm honestly upset because he made me feel guilty for all the men I dated. Am I overreacting??
