Want to prove him wrong

So me and this guy are in a complicated somewhat of a situation relationship… like we want to be together but work on ourselves anyway that’s not point rn…..! He is my sexual partner and he is my ONLY sex partner. We don’t have sex with anyone else just each other. Anyway we had sex two days ago, a few days ago and last month. So me and him have a high sex drive. At one of those times when didn’t use a condom and I said, don’t get me pregnant. And he looked at me funny because he didn’t cum but here’s the jiff… pre-cum was present. I said pre-cum can get someone pregnant it’s just a low possibility and he said there’s nothing in it to get me pregnant. So which one of us is right? Me or him
