Not wanting kids.

I’ve been dating a guy for about two months now. He’s told me from the beginning that he doesn’t want anymore children. He has a son that is 7 years old & I have a set of twins that are 2. He doesn’t see his son much due to him being a truck driver. But whenever he is off he will see him. We’re both 26. I told him I don’t want to have a kid right now but maybe when I’m 31 after I finish school and save money. He still is saying no

. Should I consider leaving him because he doesn’t want kids? What are your thoughts.
