Richard
You will have to melt yourself and let go of any ego which is coming in ur way.Kneel down before God, ask for forgiveness of all your sins and forgive your wife for anything wrong that she may have done.Plead before God to restore ur relationship.
Try some gifts.Remind her of pleasant memories.
And said, For this cause shall a man leave father and mother, and shall cleave to his wife: and they twain shall be one flesh? Wherefore they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder.
Matthew 19:5-6 KJV
Claim this promise.
Amen.
