Yet, my experience indicates the exact opposite, by leaps and bounds. Our marriage sucked prior to the affair but through my wife's repentance and my mercy and forgiveness, God blessed us both with a much more meaningful, loving and purposeful marriage. To be clear, it was because of the affair, but of God.
That's kind of my point, it's not the same, it's better. Blind trust and naivete might be lost but it was never real to begin with. We're all capable of committing grave sins against our fellow man. Some struggle with sexual immorality while others struggle with other demons and sins. I've yet to meet a couple that didn't have any struggles. I've accepted our character and our destiny. I/we can't change the past so onward we go ~~ simply doing and being better.
“To live, to err, to fall, to triumph, to recreate life out of life. A wild angel appeared to him, the angel of mortal youth and beauty, an envoy from the fair courts of life, to throw open before him in an instant of ecstasy the gates of all the ways of error and glory. On and on and on and on!”
- James Joyce, A Portrait of the Artist as a Young Man
To expect our spouse to be faithful is not 'blind trust' or 'naivety'.Its what marriage is all about, trust, faithfulness, keeping the vows made. Thats why I married a man with very strong moral values and integrity, one who never cheated despite his long unhappy first marriage. I know a lovely lady who took her life due to deep depression caused by her husbands very long affair, its one of the worst things you can do to someone.There is no excuse.
I have a good marriage. I know that after an affair, all that is important to me about that marriage would be lost. That's why Gods punishment for adultery was so dire, He knows what it does to us. He knows the seriousness. That's why he allows divorce for adultery.
Yes we all have weaknesses, but adultery is a not just a weakness, its a very serious sin, one that often destroys people and marriages. You are still married, that's your choice, many people cant stay and that's right for them.
In a marriage after adultery, something so important has been lost and you can never get that back again. Complete trust and intimacy just between you has gone.
