man does vague after hospital admission

Hi ladies,

A few days ago I was admitted to the hospital for a couple of days due to bleeding. I'm 30 weeks pregnant so it was quite a shock. They couldn't find a cause so I was allowed to go home. But on the condition to do as little as possible. I can take a short walk or make coffee but otherwise I have to stay on the couch, the nurse told me. Now it's strange that my husband has been acting weird since my hospital admission. He's short and distant and if he says anything it's criticism about pointless things or a snide remark under the guise of a joke. I have no idea what's going on so I'm curious what you all think. I'll eventually have a talk with my husband but he's really bad at communicating. So I already know he'll get angry right away and I can't deal with that right now. I'm curious if you have any ideas about what might be going on..
