god please help me heal and forgive my husband on betraying our marriage

Married 7 years and I have been fighting to keep this marriage alive. Learning of recent devastating news to our marriage I find myself crushed and wondering if I can forgive and make peace. I pray that god gives my husband patience to let me heal and understanding of the great pain he caused me. I pray for god to help us put the past behind and help us build a happy marriage. How is it that vulnerability can bring us so much happiness but yet it can open us to so much pain.
