I am only 1 year in from BD. My W has shown nor remorse or regret and I know that she will not for sometime, if at all. Not one single, "I'm sorry" about anything. All your fault Watcher. The OM is a product of this bad marriage, and that is a product of you, Watcher. I fled because you had anxiety, Watcher. I have debt now because your anxiety forced me to flee, Watcher. Etc, etc, etc...
No acknowledgment of her behavior at all. I agree, it would be meaningless to hear. She has to show it through actions.
