I wish you the best... You have to go on with your life, God doesn't hold your accountable for the actions of your W. I've been in similar situations but never have gotten to the point of a D. I believe the combination of moving out of the house and losing contact for months or weeks at a time was destructive. Just my opinion... As the male you have to lead your W and pull her through these situations, it takes a man that is willing to go the extra mile not for your well-being but for the well being of the person you love. Losing contact you lose the opportunity to help. Try to stay in contact with her... Also the changes that you made have to be sincere. Don't revert back to the person that helped destroy your life but instead become that better man and your life will get better with time. Just trust and obey!!!
