3 missed miscarriages later

My husband and I have been together for about 4 years now. From dec 2018 to dec 2019 we lost 4 babies in a year. I healed from my miscarriages but I never thought about whether or not my husband did. As each miscarriage went by I noticed my husband became less caring, didn’t touch me as much, and less loving. He wasn’t being mean or nothing he was just distancing himself I believe. Well fast forward to today. I’m currently 8 weeks 1 day pregnant. My husband finally told me a few days ago that he didn’t realize how much the miscarriages affected him. He is petrified of me miscarrying again and he is scared that if it happens again that he will have a mental/physical break down. He apologized for being distant because he didn’t realize he was doing it. Idk how to help him. I told him maybe he should do therapy. Does anyone else have any advice?
