Sorry, this ended up being quite a long post.

I don’t know what advice I am looking for and simply wanted to share this with other people to see if anybody else has ever experienced anything like this?

MIL, who is past retirement age, has a not so healthy relationship with weight and food. There are reasons I say this which I won’t go into, but let’s just say it is off topic for this thread.

I put on weight recently, but my BMI is in the green, right in the middle. This comes after years of being underweight, at times dangerously so, and struggling to put weight on, for reasons that are also off topic here.

MIL is now constantly asking me how the weight loss is going, measuring me up with her eyes, essentially fat-checking me… she does try to be discrete about this but I’ve seen it happen. She will ask whether I have managed to lose any weight since the last time she saw me. She then confirms “but the weight is going down right?”

She herself is not underweight for her age but is on the thin side.

In her fridge and cupboard, she keeps lots of out of date, expired food. Often mouldy. She will tell anybody who listens how she doesn’t gain weight and how proud she is of it, then going into details about how she manages to do that. For example, if she has eaten a lot one day she will try to not to eat very much for several days thereafter.

Unless she eats out, she’d does not eat “real” food, instead snacking on things like tomatoes or biscuits or nuts, or if she decides to have a meal, it will be something like canned soup. My understanding is she doesn’t really know how to cook, but that isn’t something you can judge her for because not everybody does.

She will often go out of her way to make sure her son (my husband) gets food when we are there, but will essentially do the opposite with me. This used to happen even when I was very thin. If we would go out for a meal she would order something “healthy” then try to eat my food and actually verbalise that she won’t take any from her son’s plate because he needs it. She would encourage her son to get the most expensive and substantial option on a menu, and although it has never explicitly been said I always feel that I am supposed to pick something cheap, sometimes based on suggestions she makes but mostly it’s based on experience from eating out with her and the sort of obvious conclusion you can draw from the behaviour when I do get something that isn’t the very cheapest option (she tries to eat my food). Of course it is possible this is all in my head but I am fairly sure it is not.

I feel like there’s an aspect to this which comes from a need to hoard food because food costs money. Or making sure you get your money’s worth (since she paid for the meal). So her son eating is getting your moneys worth, me eating is not. This behaviour extends to other situations but again it’s a bit off topic.

She does offer me what is in her cupboard and fridge but as I say it’s all expired and mouldy. In the same breath she will talk about how to ensure you don’t get hungry by snacking on small amounts of food like sweets and nuts.

On our most recent visit she made her son some food (tinned soup). She did not offer me the same. She then told me to join her while she ran some errands, in what felt like an attempt to distract me from eating. At this point it was late afternoon and I had not had anything to eat all day. She later offered me tomatoes and crackers.

I don’t think I will ever try to “set a boundary” because to some degree it is a lost cause and I don’t want to make her cross, I mostly try to eat before and after seeing her, but sometimes there isn’t time to do that.

There are definitely financial/tax advantages to having grandchildren. Google it if you don’t believe me (I just did, because your comment made me doubt myself 😉)

There really aren't, assuming this is in the UK. Perhaps if you link to what you saw someone will explain what it actually means? There can be all kinds of financial / tax advantages to leaving stuff to people before you die (live seven years and there's no inheritance tax, that sort of thing) but there's nothing where it has to be a grandchild specifically.

Look up what you would pay to give birth in the US (not to mention the maternal / infant mortality rate - quite a bit higher than ours) and I think you'll want to abandon that idea. Plus there's automatic birthright citizenship - people who are American citizens but haven't lived there since infancy still get chased to pay tax there etc.

While there are a lot of issues with the US in general and health care in particular, if you can afford to pay or have good health insurance the quality of care is as high or higher than the NHS.

Given the MIL's wealth but also batshittery, I think the hypothetical residence status of this hypothetical baby means nothing should be ruled out right now, and certainly not on the basis of cost.

People might get treated in nicer surroundings or whatever in the US, but actual outcomes don't appear to be better: we have a higher life expectancy, and we're quite significantly less likely to die giving birth: 12 maternal deaths per 100,000 live births, as against 22 there.

OP’s children will automatically be US citizens from birth no matter where she gives birth because she is American and meets the residency requirement.

Just ask her straight out wtf has your weight got to do with her? Tell her you have more interesting things to think about than someone else's weight. In fact I would make a point of calling her out every time she gives you the look. Some people are so fecking weird!

The only reason this woman is in her life is because she married her husband. So he should be dealing with it. If it’s anything like most mumsnet marriages then the OP is probably carrying most of the mental load and doing most of the day to day drudgery in her own home. She should be taking on her responsibility of dealing with her nutjob MiL as well.

Touch the food on my plate and you get a fork stuck in your hand. I can't stand people who think it's OK to touch OP's food or pick at food when you're dishing up.

Sounds like you need to distance yourself from her and pay for your own food / bring your own food everywhere. If she questions it, just reply that you're not wanting to discuss food or diets. I feel for you, this sounds really frustrating.

I’d agree with saying that your DH can visit her on his own. She’s toxic and you don’t need that.

Parallel situation for me. My MIL is such a food controller and general life controller that after years of problems we stopped staying overnight and then stopped going for lunch (this is the short story). We now go for just a cup of tea in the afternoon and only stay for lunch on her birthday when we bring the lunch - this is a huge fight though as she likes to give us horrible leftovers and food that has gone off. We recently stayed with her overnight for the first time in about five years but the only way we could do it was as a Duke of Edinburgh practise - told her we were camping in her garden and cooking our own food so the children could practise for D of E.

This has made it all more bearable.

I suffered nearly two decades of controlling and coercive behaviour and it took me a long time to realise that she was massively controlling and that I could push back. Some of the things that she has done will never leave me and her behaviour to her disabled son (husband's brother) was beyond the pale - he was paralysed and despite us trying to push back via safeguarding she controlled everything. Seeing her shove food in his mouth and then tell him he couldn't have pudding because it would 'make him fat' when he was wasting away was not pleasant. And this is the smallest part of the story.

I feel really sorry about your situation. Well done for being as patient as you have been. There is no ideal solution in this case and you are doing a brilliant job. All I can say is that there is no easy solution and you'll just have to feel your way.

p.s How old is she? Mine is 92 and grew up with a retinue of staff and not much attention from the parents (she told me her worst day of the week was the day the cook had the day off and her mum had to look after her) and during the second world war - weird attitude to food that I have noticed in other old people who went through rationing and food shortage.
