My MIL has rows with just about everybody. She has at least five siblings but is only speaking to one. She has three adult children but two have cut her off (first DH and then his younger sister). Her eldest daughter (the one she speaks to) has had two divorces and both exes blame MIL for interfering in the marriages and SIL for taking notice of her mother (this was the reason the younger SIL cut off MIL, she spoke badly about her DH and his family, tried to cause trouble) and, when I knew MIL, she had been ostracised at work.
I’ve just found out that olderSIL’s eldest has now cut her off for saying nasty things about her dad (one of SIL’s exes).
Why do some people do this? It’s not normal to have this level of ostracism in a family is it? I have a really small family (parents dead, one sister) so I don’t lnow and it’s not the sort of thing people talk about. But I can’t believe it’s normal.
