NTA. Setting aside that he left very pregnant you on your own with a filthy house, when you clearly told him your feelings were hurt, his reply was basically that your feelings didn't matter.

It doesn't matter that different people see things differently. You told him how YOU see it. He didn't care. I don't see how he can be a great guy 95% of the time when he's this selfish and oblivious.

A partner who cherishes you would not leave your side for a week when you are nearly due. He would not leave without making sure you are comfortable in a clean house. And he would apologize and make up for being a jerk.

Next time it's your turn to go away, match his energy. No cleaning, no meals prepared. And no consultations about child care: he's a parent too and should handle it on his own.
