Angry with husband

I've been telling my husband everyday for the last month or so that I desperately want to have another baby. We have a two year old daughter. His first reason for telling me no was that "having a baby is too expensive" we on our own home, have good insurance, he makes very very good money, and I saved basically everything from when our daughter was a baby. Plus I did one of those baby cost calculator things and showed him they really aren't expensive the first year. So now his new reasoning for saying no is that I am being selfish and taking away from our daughter if we have another kid. She does gymnastics and he wants to put her in private school and he says that won't be able to happen with another baby. And he keeps saying "the one we have is perfect why would we need another one? We're not having another kid" So I spazzed out and said I would divorce him over this because I refuse to only have one and he said "fine we can have another one in 5 to 10 years" I absolutely refuse to have a 12 year old and a newborn, having them 7 years apart is still too much for me. When we were dating we talked about having 3, after we had our daughter we agreed on only having two. Now he only wants one. Am I overreacting?
