help baby lose and distance

We haven't even lost the baby yet. We found out our baby has trisomy 18 and we have to decide what to do. I feel like my boyfriend and I are already becoming distant. I feel we are strong enough to get threw this together but the last couple of days has been very difficult for me. I feel like I am unintentionally pushing him away. I feel so alone. This is the hardest things I have even been threw. Any advice to help us get threw this please
