then she is asking me if she can go to a party that her best friend is throwing for her work friend. That is right she is asking me if she can go. She knows that I am taking the kids to another event that night too.
Does she normally ask your permission to go to a party? Frankly, it sounds like a WW setup to me. Don't tell her a thing. Number one, if she knows you and kids will be gone......and she is a grown woman, why would she ask? Based on other people's history, she is up to no good. There have been other WW's who claim to have drank too much and pass out on the friend's couch, thereby, having to spend the night. When in reality, the WW and OM would be spending the night together. It's when the WW suddenly asks you if you care if they do something, that your antenna needs to go up.
No, do not tell her you want her home with the family.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
