Frustrated 😖😢

I'm 33 weeks. My first child, I'm due March 24th. I'm frustrated because me and my child's father live in different cities. However I always have to give him gas every single time he comes to take me to my appointments I feel like that's not fair. How can I expect him to help w the kid when he can't even afford gas to take the kid to the hospital. What do I do? Should I just buy everything on my own or wait for him to step up?
