Hope, great attitude on putting the tree up. I am doing the same, and what do you know? W wants to come over and help. First time ever.
I think you're spot on with the complaints of being "uncomfortable". I just returned from Thanksgiving at the ILs which almost didn't happen because she is "uncomfortable" there. I am very fortunate to have a good relationship with ILs. W even attempted to sell the idea of OM to her brother. I don't think anyone was buying. ILs have been very respectful of our sitch, but have also been very supportive of me.
This sort of creates a problem though because the only person approving of OM is OM, and one slutty friend. So she circled the wagons around the three of them. Her loss, because I am finding new friends now that I'm not weighed down by her negativity.
Hope the dinner goes well.
