His virginity lie

My boyfriend told me he lost his viginity to someone else and I was always jealous of that, 10 months into our relationship he told me he was lying and that he was actually a virgin when we met. I was happy I was his first but so mad he lied to me for so long. 
Recently he was talking to this girl and (it's always stuck in my head he likes her) I asked what they were talking about and he got mad and called me a jealous bitch, then I got mad. What right does he have to get mad at me when he lied to me about it for so long imprinting it on my mind. We haven't spoken for a few days, but I feel like I haven't done anything wrong! Am I over reacting?
