I don't want to seem like a fool for wanting my M to work, I know that some here, probably think I am crazy after all that has happened.
This needs to stop too man. No one should think you are wrong for wanting to save your M and keep your family intact. That is an honorable pursuit.
While traveling that path, you must still confront the brutal reality of your W's actions. Can she work through her issues, realize she was wrong, and take the steps to (a) earn your trust back and (b) do everything she can to keep this from happening again?
