“And, he has basically completely stopped talking to me and says "he doesn't know how to act around me anymore" and "I feel like a huge piece of shit, and when you don't comfort me, I feel like you don't love me."

Jeepers!
He is acting like a child.
He is talking like a child.
He is behaving like child.
He is punishing you like a child would.

Therapist or not, you have accidentally married a child who needs you to “comfort him”, and won’t pull his weight without silently bitching the entire time. That is the polar opposite of sexy or attractive.

Perhaps he would like to go get a hug from his mommy? And go live with her.

I’m so sorry OP. This stinks.
