I want a baby, but my husband doesn't

So me and my husband have discussed having children. We always said we wanted them and I feel ready for a child. Well my husband went through some trauma in his childhood that I will not say. It left him with a lot of panic attacks, flash backs, and nightmares. Well a few nights ago he was having a nightmare and I tried to wake him up. He freaked out and punched me. He had also wet the bed. He felt awful and embarrassed. The next day he told me he doesn't want to have children anymore even tho we had talked about trying. He says he doesn't feel he can mentally handle a baby, especially after punching me. I really want to put his mental health first, but what about my needs... I want a family.
