Hi janie
What an amazing story and such a tough journey. Often things are not as we expect but I also think that very few people have the perfect marriage. most of us have had bumps along the way. I have two daughters and so want them to marry their prince charmings but i don't actually believe they exist. we are all individuals with issues at various levels and I think they become more obvious in marriage.
I can't imagine getting thru something like you have just described with out a sense of faith.
when you mentioned that your husband actually decided he didn't want the marriage after 20 years I thot how ironic...you where the one who initially where unhappy and yet battled thru. that must have been so difficult and you must have felt somewhat angry. I applaud you for letting go and letting God...you certainly needed some help...good on you for not letting go
