Thank you, I’m hoping she won’t, MIL knows a bit about her previous behaviour from some of the dramas I had around our wedding planning, so I think she would take it well.I think (despite the fact it may feel a little embarrassing), your MIL won't feel any lesser about you from such a strange message if she receives it. Well done for sending the message, and again, I'm sorry you're in that position. You deserve to have a lovely Christmas, despite what your mother is telling you.
I would just feel embarrassed and somewhat guilty that because of me, this person is in their lives and sending them messages. I don’t want them to think of me as a cause of trouble I guess.
You’ve all been super kind, thank you so much for listening to me rant a bit and offering some great advice
