Hannelore, you couldn't be whiny if you wanted to...you have real concerns and a heart bigger than anyone I know. I had a thought of hope...look where you were not too long ago with your own marriage. You thought there wasn't hope and I remember hearing such heartache in your words. Look where you are now.
It's possible that perhaps your son and DIL may come around and work through their problems, too. Especially, since there's a darling child involved.
Is there any counseling? I can't remember if you said so.
The bottom line here is what's best for your granddaughter? Something for all to think about. I'll be praying for you and your family dear heart.
