Whatisthis, I'm sorry about this situation. But it doesn't sound as if anyone is going to keep GC away from you. Please enjoy the time you have with him and don't stress out about what "might" happen.
Ok, maybe it's good to realize you might lose contact with him at some point. But that will probably only be for a while if DS gets divorced and gets visitation. Then he can share some of his visitation with you. But hopefully, they'll work out their issues and all will be ok.
Please continue to avoid taking sides, as that could backfire on you badly. Clearly, DS has ideas about what he wants to do and DIL knows what she's willing/not willing to do. They will figure it out their own way. Your only "job,' IMO, is to get along with both, and just enjoy GS as much as you can when you see him. Cherish every minute, no matter how few. Here's hoping all works out sooner rather than later.
Have any of you got all electric cars? Pros and cons please.
