Husband doesn't want anymore kids

Momma
So my marriage is on the rocks right now anyways because my husband left due to him being unhappy. Well after galavanying with a gf a week after he leaves me and is with her for 5 months he decides he wants to Come home. While he was gone I got.my hopes up that one day iwould finally get to have another baby. I told him when he came back in counseling that I hadn't changed my mind. And now he's telling me if I need a baby to make me happy then he understands but he just doesn't want anymore. I'm in a horrible Rollercoaster of emotions. Advice?
