Actually, what the Church wants you to do is get to the root of the problem - what is the cause of the screaming, the belittling, the humiliations? What’s going on, there? Can it be fixed? (If not, the Church certainly encourages that the other partner become safe, and this could include getting a divorce, and even a new identity.
I certainly agree with you that truths need to be told, here. Reality needs to be addressed head on. We can’t pretend that these things aren’t happening, or that they are no big deal.
A conversation has to begin, in which someone says, “When you do this, I feel this.” Not that you are “making” me feel this - my feelings are my own responsibility - but it’s difficult to react positively to your behaviour when you are doing this. What need of yours is not being met? How can we work together to meet each other’s needs?
If this kind of conversation doesn’t produce any results, then you need to get counseling, and if that doesn’t work, then you move towards separation and divorce. But it need not result in that. Sometimes, all that’s needed is for the person to see himself as others see him.
I recall a case where someone videotaped an abusive conversation between a husband and wife, and when the husband reviewed the video, he was horrified. He said, “I had no idea I was treating her like that. Thank you for letting me know,” and he took steps to improve his communication style with her. As far as I know, they are much happier, now, and still married.
