Praying Gods will for my marriage don't want a divorce but husband does

Praying Gods will for my marriage don't want a divorce but husband does - husband and I have been married 4 years have endured a "forced separation" due to conflict between my husband and son. My husband is seeing someone and recently told me he has divorce paperwork and wants to file. He has stated that he does not want to come home and asked if I expected him to come home and act as nothing happened. No I do not expect this. I am praying for the chance to resolve our issues and have a stronger and better marriage. I love my husband and want us to learn from our mistakes. I am praying that God will tear down the walls, soften hearts and change minds. May he cover my husband in His blood and help us both to seek His guidance and direction. May He guide us because I know nothing is impossible with GOD. Praying that God shows us the way and helps me to stay in HIS will. May he grant us HIS peace and healing and restoration. In Jesus name I pray Amen
