Is this normal?

My husband is a very lovely man. We have been together for almost 10 years and this is our first baby. He's been wanting a baby as much as me. However he's been weird about some aspects of this pregnancy. When I first took a pregnancy test and it came out positive I tried to show him the test and he was like "Eww you pissed on that, get it away from me!" Then later on when I would have acid reflux or go to the bathroom more often he would never want to hear about it and say I was exaggerating. He is usually sweet but sometimes he's a giant douche bag. I don't know if it's because he doesn't know how to act or he's nervous. Just wondering if you ladies dealt with this at all.
