It takes two to make it, but only one to destroy it. Two people don't have to end a marriage, only one needs to file for divorce and it shall be granted.
It takes two to marry, and it takes two to keep the marriage going!
What is wrong with some folks around here?
This couple was married 28 years!!!!
Of course the marriage was not 100% perfect, What freaking marriage is?
It took him 28 years and 5 kids to figure out he didn't love his wife but the teenage girlfriend?
This man is obviously in some sort of crisis of catastrophic proportions for everyone involved. He is a royal fool, but he is not alone. Sadly, there are many joining this guy everyday and it's not gender specific either.
Dear 28 years, you did nothing wrong to merit this devastation. If he fell out of love with you, he had the obligation to let you know what was wrong and you two could seek help. Instead, he tells you he doesn't love you and loves another. He made a nest elsewhere and that is why he fell out of love with you. You can't compete with the high of a new relationship. He is gone mad.
If it is not in your best interest to divorce your WS, then don't do it. Let him do the dirty deed. Some are too lazy to do the leg work themselves. I would think his retirement is more than yours and that alone would stop me from filing. Look into that. It is all business now and business has nothing to do with love. It's time to look after your best interest and not accept what he wants or needs.
It seems that for most of your marriage everything in that household was done HIS way. Well, it ain't his household anymore. He demoted himself by cheating on his family. He didn't only lie to you all these years, he lied to his children!
I would say good riddance, but not if it's NOT in YOUR best interest at this point in time.
