The above quote is not anything new - not at all. 15-20 years ago when I was in a really bad marriage to an elder we actually did separate for a while. This was not encouraged and we did keep it hidden for a while. It didn't work of course. He thought separated meant that we just live apart but since we were still married he had a right to his "due" and could come over for sex whenever he wanted it.
I was so depressed after years of living with this man - in silence because I knew the other elders would side with him and remind me of my wifely responsibilities. Ugh shudder.
I was very suicidal but realized I did not want to die. I just wanted out of this terribly abusive marriage. I knew that even if we got a divorce - no matter how unscriptural I would never be free from him. He would always consider me to be his property no matter what the law said.
So yes I committed adultery to be free and to live.
I can relate to people who do go back though. I even considered it at one point about five years after I was DFed. For me the idea of going back though was more about losing family and friends and finding a way to get some of that back.
I would never have committed adultery just to be free and go back. In my case the incident turned into a rape and I felt totally degraded by the experience and by doing something that went so far past what I believed was ethical. My conscience ached with the ugliness of it. But I got my freedom.
Another aspect for me was the guilt trip of separating and his threats to commit adultery and then it being my fault = blood-guilt. I guess I thought that if I was going to be guilty of something I might as well be the one to actually do it.
Rejoice in the healing and not in the pain.
Rejoice in the challenge overcome and not in the past hurts.
Rejoice in the present - full of love and joy.
Rejoice in the future for it is filled with new horizons yet to be explored. - Lee Marsh 2002
