I really could do with advice.
My MIL - who we live with - has lung cancer for the second time, angina, COPD.
Despite shielding being officially paused, she's recently been told by her consultants to begin shielding again as we are in a high risk area and she's pretty much the most extreme high risk category.
She's always been a bit childlike and also a kind of head in the sand person, she can also go from 0-60 quick to anger. This isn't really about our relationship, I do like her and admire she's a loving and hard working person, although we've had many problems with her being controlling regards our DC, thinks she knows best, does stuff behind our backs etc.
On the first lockdown, she mostly stayed in although went for walks.
Since she's been told this though, she's refusing to follow any of the rules (we are in local lockdown area). Says "it's been going on too long", she's "fed up of it" etc. Someone she trusts told her it's nonsense. She doesn't watch news or use internet and just gets aggravated when me or DC try to tell her. No dementia or anything. Apart from her, we are very cautious and follow guidelines.
She is regularly visiting family members in their households with multiple other households present at times, going on public transport and to numerous shops (only against her consultants, not rules), not distancing from people.
She often tries to get DC to go with her (pre teen), even against my wishes when I'm at work, and argues and sulks if I try to challenge it. Their father passive and just lets her.
On one hand, I understand how scared she must be, she's faced cancer twice and she wants some normal life if it has a chance of returning and being terminal. On the other hand, I am absolutely livid at her as I feel she's putting my DC and us at risk, and her moods and controlling, and at their father for being so passive. I'm worried for her, but it's her choice, not my choice for my family.
AIBU.
What can I (gently) day to her to convince her to shield and take this seriously.
In case people suggest - no we can't move out or live separate in any way for many reasons, and no their father likely won't step in as he is completely passive regards the virus anyway, refuses to tell her to go by rules regards DC.
The DC don't always say no to her. I try to get them to, and I hope they do.
