Your mil (unless it’s an emergency) was being unreasonable.
from my own experience @Candy155320 I think it might depend on her age/circumstances. Has she always been like this or difficult in other ways or is this newish?
Iv known a few people who have become less confident and less able to cope with their emotions ans they have gotten older and it can make them difficult to deal with.
I absolutely don’t think it’s true of everyone and am not being judgmental about it.
as a couple of example’s
my own mil has really changed in the last few years, she was always a very independent with it woman who raised her children single handed and even in retirement she thought nothing of for example going up on the roof of her shed to refelt it!
Then she had a health blip and now gets very anxious with very little cause when small things go wrong she ruminates on them and mentions them even weeks later sometimes. If she can’t get one of us on the phone she tries to control herself incase we get frustrated but her brain jumps to she must have done something to upset one of us or another reason that is equally unlikely rather than we’re just busy or hadn’t heard the phone.
theres nothing I can pin as to why except she getting older now so feels more vulnerable maybe?
my dear older friend who iv known for 20 years and used to visit regularly, she was a hippie feminist powerhouse of a woman but Covid has completely wiped her confidence to the point she barely goes out anymore and I feel like I’m talking to a person I hardly recognise sometimes when I can get her to speak on the phone to me.
maybe none of this post is relevant to you of course. In which case please ignore!
