K.G.
My husband was less sensitive, but I was also different during my second pregnancy. We had to work through it. I learned that I had to tell him EXACTLY what I wanted and needed so that he knew. Otherwise, I would get upset and he would be confused and hurt. Also, both of us shared duties raising our son, and sometimes I needed him to step it up. I told him. I didn't wait for him to notice. (I would take pride in digging under the couch for lost toys. I would almost get offended if he suggested that I shouldn't. We had different issues than you.)
With my third, I was in pain almost the whole time. He definitely got sick of it, and so did I. We ended up talking a LOT, both of us explaining how we felt, what we needed, and how we needed to work with each other instead of get annoyed. It was tough, I'm not gonna lie. But it worked.
