Am I The A$$Hole

Im a SAHM, my husband is in the army and works M-F usually around 10-12 hours a day. We have a 14-month old and I just found out I was pregnant (8 wks).

Recently I've been constantly nauseous, extremely fatigued, and overwhelmed by everything. Also note, I've been weening our son for a week now and he also decided to start waking up at 4 am every night.

That brings me to last night. Our son woke up. And my husband starts getting mad. He has to be up in an hour to get ready for work and our son is screaming, going in and out of sleep. What does my husband do that pushed me to the edge? Well, he told me to "take him downstairs". I, of course said, "no, we're trying to sleep too". He then proceeded to call me "Selfish" and "inconsiderate" (because I wouldn't leave to let him sleep). Am I the A-hole For not going downstairs to sleep on the couch?
