S.B.
I'm not sure there is anything you can do except just not be drawn into it.
I've had a few friends like this.
One minute it's "I just can't get over how well behaved your children are and I don't know where I've gone wrong" and the next minute it's, "I know we all planned to go to the library, but there's going to be a fit if we don't go to Chuck E. Cheese instead. So, if you get there before us, save a table."
In situations like that, I just said I was glad for the call because we wouldn't be able to make it. And my kids and I went to the library anyway. My kids weren't fit throwers and did understand that sometimes plans change, but over something like that? Nope. What about what MY kids wanted to do?
I think your friend is in for a world of hurt that she can't even imagine.
It always comes back to bite parents in the butt who are afraid to say no or cater to every whim, for whatever reason.
And, one of the consequences can be people deciding not to get drawn into it.
I'm going through this with a friend right now and thankfully she doesn't live close by. Her son is totally disrespectful, rude, mouthy...and not just to her.
Her way of coping is to just give him whatever he wants thinking he will change and then she cries because nothing she ever gives him or buys for him or does for him is good enough. And he flat tells her so because he knows that he can get away with it.
She feels guilty because she works. She feels guilty because she's divorced. I've heard it all. I've heard him say the most ugly things to her even in public to the point other people are staring and she hands him money and offers to wait while he finds something he wants.
I have found that there is nothing I can say to her.
My son doesn't want to be around her kid and I hate to say it, but I don't either. It exhausts me to listen to how he runs everything and how she just doesn't know what to do.
She's a super good person and I know she loves her son, but NO is not in either one's vocabulary and what seems simple to me seems unreasonable and unfair to her.
I just stay out of it as much as possible.
I don't have to buy into any of it.
Some things are better left alone if there's nothing you can say or do to help or make a difference.
It's a tough position to be in and I wish you the best.
