You are probably staying with him because despite everything he has done, you still love him. I am not sure what you want prayer for? Do you want your marriage restored? Or the strength to leave him?

Father, I lift up this couple to you. pray for salvation for this husband. i pray that you would convict him of his sins. i pray that he would come to know you and will desire to live a life that is pleasing to you. I pray in Jesus name that this marriage will be fully restored. I pray this couple will come together and put you at the head of their marriage.

I pray you would minister to this woman. I pray you comfort her. I pray that she will lean on you and know that you are in control. You have a plan and a purpose for her life. It is good and not to bring her to harm.

Thank you Lord Jesus.
