Is it possible to see SS and the GC without DIL present, as some have suggested? It doesn't sound as if she wants to see you, anyway. I realize it might be awkward to just try to make plans with SS and kids, leaving DIL out. But maybe you could talk to SS about the idea and see what he can arrange?
You would have to be careful not to badmouth or complain about DIL. That would just backfire. Maybe just say there are tensions between you or she doesn't seem to enjoy your company.
Then again, after what happened, you may be hearing from him that she doesn't want to see you. So that may be your chance to make your suggestion.
Would she be ok with your taking the kids on your own sometimes? She might love to be "free" of them for a few hours. Maybe not. But when things calm down, it might be worth a try. Better for kids and you.
HellsBells, where in this thread or anywhere else are people being unsympathetic? Most posters seem to feel for the OP and have even sympathized with her speaking up. Some are just worried that she may have hurt her standing with SS' family, that's all.
Anger management!!! Help needed.
