My MIL has been getting bad mood swings for the past 6 years and getting worst. There mood are mainly random and anything will set them off, ( I know menopause is a big part of it but myself and others (aka her own daughter), in the family think she needs some type of help) on Friday she got upset because my SO didn't text her back right away, this caused her to go off on him when he did for 3 hours of guilt trip. She gets upset if I disagree with her on how I raise my children. We have a small 2 bedroom house and I tried to minimize how many toys kids have so we're not tripping all the time. Yesterday she brings a 4 ft tall, 5 ft long 3 ft wide old bouncy horse a for the kids as an apology to my SO bc he had one when he was little. No warning, no asking if it's ok, no text saying she was coming.
