(Long post warning) Pregnant SAHM in Need of a Break

I'm 25 weeks pregnant and raising a 20 month old son . I feel like I never have a moment to myself and have mentioned more than once to my husband that I need him to take our son out of the house sometimes. It's happened maybe once since he's born. Currently we aren't speaking to each other after getting into an argument about each of us getting a break. He fell asleep on the couch while I watched our son, when he woke up I asked my husband to take him so I could get a moment before starting dinner. He started saying I only wanted a break because he went to sleep and I'm doing things out of spite. He works so hard and doesn't get enough rest so that's why he's tired. Which I understand, but why does that mean I don't get a break too? After fussing for a few moments in front of our son, I said I'm done took our son and went upstairs. I told my husband to enjoy his break. I eventually came back to make dinner, but my husband didn't even looked or speak to me. Even after I made his plate for dinner, I ate in the kitchen while he fed our son. I'm kind of at a loss for how to resolve this. I really don't even want to talk to him right now, and he really hurt my feelings by pretty much discounting my need of time to myself. I guess I'm venting more than anything. I'm worried what it's going to be like when the new baby comes now.

Sincerely,

Tired Mommy
