I’m sorry for what you are going through. I have been out almost 20 years and I can’t imagine a situation where I would allow someone to treat my spouse so disrespectfully. I am “just inactive” too, but still shunned by some of my relatives.
I think it’s ridiculous that you and your daughter are being treated this way. Of course not being invited can also be a gift, and I am betting your daughter will not soon forget this, further insuring she won’t join this cult.
