I have no idea what the circumstances are that would cause your wife to tell you to leave but, you need to stay strong in your faith and belief that God can and will heal your marriage. Is someone else helping your wife? She shouldn’t be by herself her being blind and all.
Sweet Jesus lay you healing hands on this marriage that so that it will be healed. Help the two to keep their faith in You and know that Your will will be done.

I pray in Jesus’ Holy Name that you find the same strength that your mom has. She will need your strength more than ever to help her through this..You are stronger than you think. Jesus please be with this mother and daughter let them feed off of each of others strengths. Amen

Please don’t give up! God, has a plan and I know that in time He will bring your daughter back to you. My sister is going through the same thing with her grandson and I pray for her also that this thing between them be resolved.
Heavenly Father please be with this mother as she goes through these hard times. You have been there for me through all of hard times of my life including the one I am going through now. You have given me strength and hope please God help this mother.
