Fearful husband says it’s hard to look at me

My husband shared with me this morning that he is so afraid of having a child that he has been avoiding me. I am 18 weeks pregnant and he says every time he looks at me and sees my belly he is acutely reminded of this fear. I understand being a little freaked out - making a little being can be very frightening at times, but now I feel very alone in this pregnancy. We decided to get pregnant together, and now scared he is having second thoughts (a little late). Help from any mamas that experienced this fear in their husbands would be sooo helpful!!
