One last thing you ought to think about - come to agreement with your husband about what answer he is to give when asked "Where is LeeLee?". Because he will be asked when he shows up alone.
It probably should be some form of "she had other plans" because if he says "she is too stressed to socialize" the advise emails will come flying at you!
This, for sure. I mean, Alice doesn't need to know that your other plans are sitting on the sofa watching moviess. If he's pressed on the plans, he can just keep repeating.
Alice: But where is LeeLee?
DH: She has other plans tonight.
Alice: What could POSSIBLY be more important than being here?
DH: She had other plans made already.
Alice: But where is she? What's she doing?
DH: Where she is and what she's doing is her business. Her plans kept her elsewhere.
Alice: When will she come to another party?
DH: She'll have to check her plans. I'll make sure to relay your concern to her.
And then you and DH can have a good giggle about her "concern" about your absences.
