I would like offer my opinion, as someone coming from "the other side". A whole different perspective, if I may.
I survived 14 years of domestic abuse. I know, from personal experience, that it is the verbal/emotional abuse that completely destroys one's spirit. I would gladly have taken hundreds of black and blue marks over the verbal assaults that I received. Every domestic violence survivor ever asked has said the same thing. By the time a man crosses the line into physical abuse (even something minor, like shoving) and the woman can finally be protected by the law--it feels stupid and laughable, because that for which the cops will actually come for and the courts will step in for is so minor, it is nothing. The woman has already been pulverized and beaten to a bloody pulp, day after day after day--the bruises just aren't visible.
I don't wish to offer you any false hope here, Dennis, but I also distinctly recall spending 14 years of marriage always trying to reconcile with my husband. I filed the orders for protection but I always let them drop when I thought my husband was going to take things seriously. I did separate from him one time but I moved back home after three months. Eventually, his drug use became so bad that the county stepped in and told me that either the husband had to leave the home or the children would be removed from the home. I helped the husband pack his bag. He was civilly committed, and bounced from one treatment center or psych ward to another, and we were locked into the courts with a child protection (CHiPs) order for a year and a half. I STILL did everything on my part that I possibly could to try and reconcile with that man. Only after having to stand on my own two feet and having some distance for that last year-and-a-half was I finally able to see that my husband really was never going to make any real change. His own children would have nothing to do with him, even when the judge ordered supervised visitation. A month after I started divorce proceedings, my husband went to a hotel (with another woman), and died from a drug overdose.
Now, what I am NOT getting from you is: rationalizing, minimizing, or blaming everyone and everything else under the sun. I really think there is hope you. It also sounds like you have had many years of a good, solid marriage. Unless there is something you haven't told us, I am not getting that "abusive" has been your MO all these years.
Remember: "I'm sorry" (like "love") is a VERB. Show REAL fruit in keeping with repentance.
