Boyfriend doesn't want to be there on baby boys birth

So my boyfriend who is also the father of our first born doesn't want to be there when I deliver our baby boy. He asked that my mom goes. I am due in February and I feel like he is so insensitive for saying that. Then again, he talks big about how manly he is but he's actually a wimp. He almost passed out when we had our daughter. He couldn't watch the actual birth because he has a weak stomach. I guess I have to ask my mom to come stay with me the whole time. Anyone else's significant other can't be there or doesn't want to be there? Ugh
