I know this may not help you much, but yes, in many ways I know what you are going thru and my heart and prayers go out to you. My wife told me she wanted a divorce after 18 years. I was angry, hurt, and depressed by it all. I wanted her to change her ways and her mind. I know, after much soul searching, that I can do nothing about it. You see, its all up to the Lord Jesus. I have come to realize that and God has given me peace about it after much prayer. I have no clue if she will ever come back, but I know the Lord will take care of me and my family. The best advice I can give you, is get on your knees and pray about it all. Give the Lord a chance to heal you and your family. Let the Lord work on your wife. Pray often when you feel weak and let the Lord help you. I love you my brother in Christ. May God bless you!!!
