unsupportive boyfriend?

im 6 months pregnant and my boyfriend isn’t even interested.. like i could see the baby like kicking in my belly and i read that it’s good to talk to her and i asked him to talk to her and he said “i dont know what to say” and i told him to tell her about his day and all he said was “she don’t even understand any of that we don’t have to talk to her”. i told him it’s healthy to do that and he still doesn’t care. he never puts his hand on my belly and never talks about it. it’s so hard idk what to do or how to even feel about this.
