Husband has thrown in the towel!

My husband and I had a serious conversation about our miscarriage and what we would have named our baby boy . And each time my heart sinks a little. He refuses to try again and says he don’t want to have the same thing happen again. Maybe I’m selfish but I told him that I would like to at least try. He’s not hearing it and pretty much shuts down when sex and baby are in the same sentence. I’m ovulating this week and he has kept his distance from me and sleep with his back turned. I don’t know what to do. I just want to smile again .
