Prayer for sadness and for marriage reconciliation

I’m going through a break-up. I need prayers for my wife (Kassi) to forgive me and give me another chance in our 8 year relationship.  I know that I wasn’t a perfect husband but we have been through more together than anyone could imagine. Yet we held on and never gave up. God blessed me with her and I know I should have paid more attention to her. But please pray for reconciliation in our relationship. I’m taking this pretty hard. It’s taking its toll on me.
