Married but I feel like I am having this child on my own!!!

I set up the nursery by myself! All by myself!!!! My husband did not do absolutely anything! He watched me struggle to assemble the cot bed, Moses basket, swing, chest of drawers and everything by myself... I had been telling him for months to set everything up, he didn't seem bothered. I am 7 months pregnant so I couldn't continue waiting for him and had to struggle doing it on my own. Now he is upset because his budget for the nursery furniture(cot bed, mattress, pram, and cot changer) was $500 and I ended up spending $1000 buying these things and he had to pay. How did he expect that all those would be $500? Now he is saying that he will return them all and buy used items because they are cheaper. Ughhhh he annoys the hell out of me!
