Men and Pregnancy

I am having a really hard time right now because my husband doesn't show any excitement at all that we're gonna be parents. He came with me to my first ultrasound and all he said was "good job" and it was directed towards me meaning great you did it for once instead of miscarrying. I don't know if it's my hormones or what but this really hurts me. It's scares me and makes me cry and I don't know what to do. Does anyone have any tips for me. Please.
