he wants to get me pregnant

My SO use to be so against me getting pregnant like when I say so against I mean it , but anyway we got in a big fight the other day and at the end  he told me he wanted to marry me and have kids with me and then we had make up sex of course and then he said I want you to have my kids and he kept saying do you want me to get you pregnant and I'm get you pregnant  and he busted in me ,  should I talk to him about having a kid or should I just leave it alone ?
