DEAR ABBY: Our son, "Philip," has been married for two years. He recently informed his wife, "Karla," that one of his co-workers -- I'll call her Sarah -- is pregnant with his child. Philip says he still loves Karla and wants to stay together, but he feels an obligation to the other child. Karla is now pregnant with their first baby.
The problem is, Philip is spending most of his time at Sarah's home caring for her, and very little time with his wife.
My wife and I don't know how we should handle the relationship with the two grandchildren. What are our obligations to each? Should we treat them both the same? By the way, my wife and I have never met Sarah. -- DOUBLE-WHAMMIED IN PENNSYLVANIA
DEAR DOUBLE-WHAMMIED: None of this is the fault of your grandchildren, so think with your hearts and treat them equally.
Forgive me if this seems pessimistic, but from your description of your son's behavior, I seriously doubt that his marriage to Karla is going to last. So don't worry about not having met Sarah. If he continues to spend the lion's share of his time with her, the chances are good that you'll be seeing quite a bit of her in the future.
