Thought he wasn’t ready for kids

My bf and I have been together for almost a year now and we’ve discussed that we weren’t ready for kids rn but if it happens we’d just accept it. We’ve been having sex without a condom for a while now and he would just pull out because I’m not on any birth control. Recently we’d be having sex and 5mins later he’s telling me he cummed inside of me which I’m thinking in my head is crazy because he said he’s not ready for kids rn and is very careful when pulling out. He did it again 2 more times and would just tell me hey I just cummed inside you... do y’all think he’s trying to get me pregnant on purpose?
