God bless u. If u are having problems in your marriage, please seek counseling. And bring all your troubles to the Lord. Maybe it is time to cut off this friendship, or don't share anything personal with your friend. God is not the author of confusion, satan is. When I was having problems in my marriages, I prayed, and spoke with Christian counselor. Even though a few of my friends knew of my situation, I knew they could not help me. One envied me inspite of my situation. I had to separate myself.
Father, we are here to please U and not friends. I pray for a godly friend for this individual. I pray that this person will read your words and act upon them. Teach this person to use wisdom in sharing the difficulties in life.
