How do I confront him?

My bf doesn't want a baby. I do. He says we're not ready, yet when we have sex, we never use a condom & he pulls out. Sometimes he pulls out just in time. I'm afraid he won't pull out one day & he'll make me take the plan b pill. He says he would want me to get an abortion if I got pregnant right now. I am totally against that. We are both 19 btw. Please give me some Tips.
