When will my husband want to have a baby?

I have been with him for 7 years married for going in 2. We have a house good jobs and a dog. I keep having baby phases that seem to be a lot more frequent lately. I asked my husband if he ever had a phase like me and he said no. 
He said he is going to keep adding projects to the house and want to put kids off till xyz is done. Then he will add something new to the list. After telling him how I feel about a baby he said it would probably be up to me to decide when because he knows he is going to keep putting it off. But I need him to be ready too. 
Anyone else go through something similar?
