Son and daughter in law separating

My son has told his wife of almost 15 year, with two young children (6 & 4) that he wants a separation and probably a divorce. He has already moved out. My daughter in law is devestated and my grandchildren are missing their father and can't understand why he has done this. I have tried speaking with my son. He has many reasons why he wants out of the marriage and really does not want to work at saving it. I don't know what else to do. Neither my son nor daughter in law have actively asked Christ into their lives but my daughter-in-law does believe in God and I believe is seeking Him at this time. I would really covet the prayers and insight of Christian women who have gone through this or who are compassionate towards those who are.

God guide my feet!

I am dating a man who is in the process of divorce. He has been seperated from his wife for awhile now and according to him, she left him. After fasting and praying he truly believes that God released him from his vow. He has already filed the paperwork and in a few months time it should be completed. We are both Christians and we both believe in the sanctity of marriage. Richard says he intends to marry me as soon as he is able and deeply wants to build a new life in Christ with me. I have never been married before and truly want to do Gods will. Is it right for me to marry a man who is divorced for reasons other than unfaithfullness. Will I be seen as unclean? I love him very much and I am amazed at his conviction to Christ. I believe that he is truly a man of God and I know that he has helped me with my desire for a closer walk with the lord. I guess I need to feel confident in my choice to marry him. I have prayed about this many times and I will walk foward in faith but, I need encouragement from anyone who has been in my shoes and knows what I am facing. PS. he has a son (7) and I have never dated anyone with children.
