Mike....I am very sorry to hear about the dissolution of your marriage. Debra Law has posted a link to a place called MarriageBuilders.com and that is a wonderful site and I have used it time and time again. I can't thank you enough Debra for that!)
The loss of your marriage, the loss of your partner is incredibly devastating no matter how prepared we are for it. But as Debra states, there is really no point in finding fault with either of you separately about who was to blame, but rather step back and look at the overall situation and how each of you were accountable or responsible.
The steps now are to move beyond the past by taking the time needed to heal yourself from the trauma. True, a broken bone will men itself on its own without proper care, but it will probably not heal properly to become stronger than before. Likewise a broken heart may heal properly on its own, but sometimes, it too, requires outside assistance to heal stronger than before.
Debra's recommended site as well as a book I can recommend, both might be useful to you.
"Starting Over" by John Gray. Five it a looksee, visit Debra's site and let us know how you are doing. We are here for you anytime.
Good luck and bless you new friend.
