I'm so sorry Alisha.
I confess my MIL has canceled her visit on Thanksgiving without telling us. Again. I already bought food for her stay here, everyone coming to Thanksgiving (it's a potluck) included her and her bf into their food planning, and I've been getting the twins excited again for her upcoming visit. Particularly after reading Nurtureshock, I'm annoyed that I've been telling them something that won't happen. But also, I'm upset that she didn't even bother to tell us.
DH called and left messages for her the day we got back, and after not hearing from her for a day or two, he called her bf who said they weren't coming and was surprised she hadn't called him back, since she'd gotten the messages.
She canceled a visit in July because she was angry with dh and giving him the silent treatment. They reconciled, so this cancellation was a surprise. The twins haven't seen her since last Thanksgiving.
