I am divorced and engaged to my new partner. I kept my previous married name due to the children who are still young.
My future MIL has sent a Christmas card to my partner and I and addressed it to 'Mr x & Mrs y'. We only got engaged earlier this year but she knows I am divorced and due to marry her son (we've been dating a few years). I found it really inappropriate to address me as Mrs, verging on insulting. It's really got to me because that relationship is over, I've moved on from a difficult time and I cannot understand why she's addressed me as 'Mrs' when I'm not and she knows that.
How would you feel?
