HELP! BF!

So basically before my boyfriend and I started dating he told me he had never had raw sex before. And so he wanted to try it for the first time with me, and since he said that I believed him and we had raw sex. Now 3 months later he is talking about his ex that he might have gotten pregnant and I said why would you even be worried cuz i thought he had never had raw and he always pulls out. Then I ask him did you guys have raw sex and he said yes. My heart honestly dropped and I felt lied to. Like did he lie about it just so he could have raw sex with me? I feel betrayed and he’s also never been tested before and he said “I wasn’t worried because if I had something by now it would’ve shown up for you”. Like I am an experiment or something. What should I do? Should I break up with him over this, because now I have major trust issues.

I know this sounds childish but I kinda want my christmas present from him first then end it? Should I do that?
