Let me illustrate this with an example: I confronted him regards his porn addiction and told him how deeply it hurts me. Instead of offering a gentle apology (even a fake apology would have helped), he turned around and told me that I am stupid as I don't understand his evolutionary need to "F**K" and spread his seed amongst as many beautiful women as he possibly can. He said that he has no control over this urge and its a natural behavior for me. Needless to say, I felt completely humiliated. I look at this incident as emotional abuse, because that's how it made me feel. Any action or word which hurts one's spouse in a very personal way, is abuse. Period.
I agree with you. That's horrific what he said to you. YOU shouldn't feel humiliated; HE should! Although I don't justify how you've dealt with this, in THAT exchange I would have told him "Well, good luck with that. I don't deserve this kind of disrespect."
You both seem to have reached a point where you're toxic to each other. This is a pro-marriage forum, so I won't go any further.
