JS, we've all behaved poorly in our MR. Short of extreme emotional/verbal abuse, and obviously physical abuse (oh and infidelity) that doesn't give a spouse a right to bolt or start an A.
So own your part, forgive yourself and move forward. Too many LBSs take the blame and continue to apologize for things in the past they can't change.
