Getting annoyed with my Fiancé!

He is completely unsympathetic about anything pregnancy related and unfortunately I am extremely paranoid and have anxiety about the baby and he just does stuff to purposely aggravate it more. Like today he jumped into the bed and I asked him to not be so rough and then he like got up and went to the end of the bed and plopped down on purpose and landed right on my feet. Realistically I know a little bounce and landing on my feet won't harm the baby but still i get stressed out and he just thinks I'm crazy which I admit sometimes I feel that way lol but why does he have to be so immature and make t worse when it could be supportive and help me feel less paranoid instead 😔
