Are you willing to do what is necessary to repair the marriage and is she willing also? Do you still love her enough to do what is necessary to make the marriage work? Is she still in love with you to the same point? Then you must work together to fix what is wrong and go on with your lives and be happy in the process. You both need to go into it with new energy and a deeper love and appreciation for each other and please do not take each other for granted. Communicate with each other and don't let your feelings be misunderstood.
