God bless you. Please don't think that God does not understand. For He experience abandonment, rejection, denial, suffering, betrayal. He experience this even in the Garden of Eden. I pray that you will lose yourself in Him, you cry to Him and in the mist of your pain, forgive your husband. John 16:33 Jesus says you will have tribulation, trials, burden, frustration, distress but be of good cheer says Jesus. This is a hard place to be, but please trust God. Because Jesus has overcome for you, you will be able to overcome. Please dont let unforgiveness, nor anger have control over your trials. Get into the word, play christian music, and minister to your spirit or satan will get the upper hand.
Father since you understand and suffered comfort her with your Holy Spirit, guide her steps and decision where it will lead to the right solution. Anoint her with the oil of gladness. I ask all this in Jesus name
