I don’t want another child

How would feel/what would you do if your spouse tell you that he don’t want another child once you get married but the whole time we were dating he constantly was saying he want a child and once we said I DO and he know that I told him that will be a deal breaker because I don’t have any kids and i feel like he told me what I want to hear so I could stay with him. I’m lost things don’t feel the same between us I can’t even look at him the same
