I was a sh!t husband and I own that and know my faults. I guess I just married a very unforgiving person who got sick of putting up with my crap, and in reflection I don't blame her.
It is not about her forgiving you. You think if she'd just forgive you and commit to the M again, that everything would be grand. You are sad that she isn't giving you a chance to prove you've changed. I don't believe it works like that. Just b/c we forgive somebody who made our life miserable....doesn't mean we would want to continue to put ourself in that position again.
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!
