My son dated his wife for about 4 years prior to getting married. They have been married for about 2 years and they now have a 2 month old daughter. He called me, emotionally upset and said that his wife moved out and took the child. He told me that his wife told him that she didn't love him anymore and that she wanted a divorce. He also told me that they had been seeing a marriage counselor, although I do not know the time length for these sessions. I live in another state and do not see them often. I do talk to them weekely, however I've had no hint of anything to suggest a problem. Now I'm distressed to hear this. I am confused to what has changed sop suddenly. Also, I'm worried that I can not be of assistance to him. I'm still dealing with the shock of the news. This has left me feeling helpless and unsure of what to say or do. I also worry that I will not have a relationship with my newborn granddaughter. I have only seen her once since she was born. I had been receiving weekly pictures sent to me by my son.

In our conversation, I did offer to be available for conversation, if he chose to call me at any time. He has hired an attorney. He expressed fear of financial stress due to this event. I do not have resources to help him financially, so I worry about his future. I truly do not understand what happened. Of course these things do not happen over night, but this has been presented to me in a sudden manor and I was unaware of marital problems.
What do you suggest I do during this time of emotional stress?

Sounds like you're doing the right thing. Even though he's your son, you might not want to be too involved. Try to remain neutral (you don't want to risk upsetting the ex wife and have her make it difficult for you to see your grand baby later). You already told him you were there if he needed to talk. I think that's the best think you can do right now.
