What words are worth staying in an abusive R? It may be words you would like to hear, but when a person has been abused, bullied and manipulated to the point they are almost brainwashed........how can you tell them to please try? Try what? What else is left to do? Do you really believe she should continue allowing him to treat her like an unloved, unwanted junk-yard dog, while he annihilates her? Frankly, I haven't seen anything he's said that would be worth a second of his terrible treatment.
He just wants to get out of paying her anything he's not forced to do, and as usual, he lies and makes her feel worthless in order to make her back down.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
