Boys😑

Guys I need help asap. There is this guy , we have been talking to eachother since November last year and about two months ago started dating, things are pretty serious and I love him and I thought he loved me. Before we got together I had a boyfriend and I gave him a handjob then he dumped me. Around that same time the guy I'm with now got a couple blow jobs from another girl. When I told him about my ex he didn't tell me about that girl. I'm hurt and don't trust him. Am I being over dramatic? He still is talking to this girl BTW but just "as friends" is what he says. What do I do?
