More unfortunately, as adults age, the ability to critically evaluate claims/facts/stories and determine whether they hold merit gradually diminishes. Older adults are more susceptible to falling for misinformation, especially misinformation that looks like it could be true on the surface and is reinforced through emotional manipulation. It gets increasingly difficult to pull someone like that back into 'reality', and sometimes it indeed means permanently damaging (or even destroying) the relationship.
They (the one being manipulated) have to be the ones to see that maybe what they have been led to believe could be causing harm to their relationships and they have to be the ones to reach out and seek amends. You can only set the boundaries, enforce the boundaries, and be ready to accept them if or when the time comes.
This is what I am most scared of. MIL is in her mid 60s, she has 20+ years of life expectancy in front of her, and it appears that she will, instead of spending time with her grandkids, dedicate it to growing increasingly crazy about all this alternative stuff she is into.
I want to believe that she would stop before actively squandering everything her husband has worked for all his life.
But seeing how this has escalated, I have my doubts.
I mean, handwritten letters about this powder added to Christmas presents and stuff like that, to me that's just insane.
As said, she's always been into that kind of stuff, but the intensity has definitely picked up.
I think it may be related to the fact that there is a specific person being her "best friend" and constantly egging her on. But I did some research into that person and she seems to be maybe just a step above in the MLM, not really someone who is genuinely making money on it.
From the overall context I am fairly certain this is still more about "privileged knowledge" than it is about money, it's more about being able to treat what conventional medicine can't/won't than it is about a get rich quick scheme.
They live in Sweden and Sweden is no joke, everyone in this chain has to keep a very detailed accounting of their "business" so I think it must be obvious to her that all that is costing her more than she "earns". It's hard to say what kind of commitments she's making but she must be buying a lot of that product because I definitely see a lot of it stashed all over the place when we are there.
There was a period when she was aggresively trying to guilt us into buying this stuff because "we could afford it" so I told her we would gladly give her money if she needed it (Swedish people do have a weird obsession with keeping their finances separate (which in this case is possibly a blessing), so it is theoretically indeed so that it is just the FIL and then us who are the "wealthy" people here while she is just an entrepreneur trying to "make it")
I mean, I have no real insight into their finances, but from the fact they're boomers with two houses and a boat and FIL seems to be actively interested in stocks and investments I'm pretty sure they are doing just fine and will keep doing so unless she signs it all over to some cult. Which is no longer a ludicrous thought, hence my horror.
I'm glad to be reinforced in my belief that it is the right thing to do to absolutely refuse to engage (because my husband seems to think that in a worst case scenario, we could just accept to pay 100€ per month for her powders and then trash them as they come or donate them away). But I refuse to do so because I do not want to encourage this.
Also it could be worth mentioning that these powders seem to be something she's been playing with for at least 9 years now but only got really crazy lately, because I am under the impression that this is the same product that she gave me shortly after we had our first son. She showed up with these two little boxes of vitamin powder, said they were really good for me, given that I was post-partum and breastfeeding and left an invoice for my husband of about 120€ for them. I was like "huh??" but he said to just let it be, but then I drank some of it and had an immediate reaction where my heart started pounding uncontrollably and I felt my skin was burning. I was scared out of my mind (I was alone at home with an infant).
Turns out it was a niacin flush and she insisted it was actually "good for me because the body was getting rid of toxins" . I could have fuckin passed out on top of an infant. Anyway, we threw away the stuff and it was the last we heard of it until 2 years ago when the whole thing resurfaced and now she wants us to feed it to our toddler.
I really believe she means well. But this is really going crazy.
