MIL manages to upset everyone at every single opportunity.
When I first met her she said - your not (husband's) type, you're too pale.
MIL asked me to go with her to buy her outfit for my wedding day.
First port of call was a very swish boutique in our small market town. She tried on a few outfits and one particular outfit looked fabulous and I told her so. She went quiet when she saw the price tag. Both the boutique owner and I were trying our hardest to get her to buy it. She didn't - her excuse was that 'she didn't want to outshine the bride on her big day'. To which the boutique owner replied, 'your daughter in law to be could wear a big black bin bag and still outshine you'.
We ended up in C&A in a large city centre (that dates it) where she bought a dress for £19.99. Her shoes and hat were from a market stall. The outfit which we had all liked was £300 and it was more than I'd paid for my wedding gown (she didn't know that).
Other 'compliments' were 'the black widow is here again' (me).
'That lipstick looks fluorescent' - it was clear lipgloss.
'I wouldn't make my son eat that muck' - I was making pizza dough and had just spent a small fortune on gourmet cheese and meats.
'You and your father could be twins' - meant to be derogatory.
'Let's go home and get warm' - she said to FIL when the darn parkray fire had gone out and I couldn't get it relit while H was at work. 'That's going to be nice, (her son) coming home to a freezing cold house when he's been at work all day.' I'd only just got in from work myself and was busy preparing a meal rather than concentrating on the fire (which powered the central heating).
There wasn't a day went by without criticism and snarky comments. I was glad when FIL divorced her and she went to Lanzarote with her new boyfriend and her divorce proceedings. My children were 3, 5, 7.
She doesn't know my children. She'd booked a cheap last minute holiday and went away the day before my first child was due because she told me that all first born children were at least two weeks late and she wanted to look tanned in 'her baby photos'. He was born the day she went on holiday. She told me I was inadequate at breastfeeding as her second son (BIL) had put at least a pound on every week while she was breastfeeding. H had been formula fed.
When she visited relatives back in the UK she would walk past my children in the street because she had no idea what they looked like. She took no interest in them whatsoever. She came back to live in the UK a few years ago and expects us to drop everything and run after her. It won't happen - she alienated our children all on her own. She gossips to anyone who will listen about how she doesn't see her grandchildren and great grandchildren. Her great grandchildren are frightened when they see her as she is loud and overbearing.
She threw my husband out of the house when he was 15 because he swore at her because she hadn't washed his best jeans. He's hardly said a word to her in the intervening 47 years. I went out of my way to include his family in our lives because all my family are very close.
She is barely tolerated - my son who was an avid Harry Potter fan pointed out, when he was small, that she was like a dementer - who sucked all the joy and life out of everyone. I couldn't have described her any more accurately.
FIL married a wonderful lady - we see them regularly and socialise with her wider family. FIL won't say much against his ex wife - just, she's a very bitter woman.
She made her own choices - now has to live with them.
