Feeling guilty??

I am currently 8 weeks with my rainbow baby! But I notice my bf doesn’t ask questions and doesn’t bring anything up about the baby and all the “what if’s” like when we were ttc? I cuddle my tummy every night and he cuddles me and feels me cuddle my lower tummy and he jus puts his hand on my chest and grabs my boob. But I think it’s cause he doesn’t wana bond wit the baby cuz he’s afraid we’ll loose it..I had my last miscarriage at 11weeks. But it still hurts my feelings...cuz we tried so hard for this baby and I have a good feeling about this pregnancy...idk it’s jus really bothering me and it hurts my feelings a lot but idk if I should mention anything to him??
