RatsCatsandPuppies · 11/09/2026 14:12

Looking for some views here, as I’m genuinely questioning myself and don’t know how to move forward from here.

Im recently married (only 9 months) to DH, and my MIL has sadly become very unwell - perhaps with only a few months left to live. SIL has taken issue with what she sees as an unfair split between what she is doing to support their mum and what my DH is doing. I can see both sides. DH believes he is doing everything he can within the constraints of his life, his sister sees it differently to that.

DH and I have talked a lot about how I can best support here, and he says the best way I can support is to take things off his plate at home (eg doing more jobs around the house, helping more with my step children when they would usually be with him/us) so that he can use that time to visit his mum and help out.

I’m absolutely fine with all of that, but the problem is my SIL seems to have totally focused all her rage on me and thinks that if DH can’t do the things she wants him to do, I should be stepping in to do them in his place. She is talking about expecting me to do things like taking MIL to appointments, cleaning her house, organising personal care, buying and preparing food for her. Her view is that everything in the lives of our children (both step children - her nieces - and my children) should go on hold (their hobbies, friends, birthdays should be “cancelled” etc) as MIL is more important. She’s very angry and sending me messages saying she will never speak to me again if I don’t “do my bit”.

I simply wouldn’t have the capacity to do everything she wants - I work full time, my own parents are elderly and infirm, I have 2 step children, 2 of my own children, and a serious health condition which I have to manage carefully.

Am I really responsible for providing my MIL with care as my husbands proxy? How on earth do I navigate this? I am trying really hard to keep the peace with everyone. But fundamentally I’m not prepared to deprioritise being a parent and if I get sick myself then I’ll be no good to anyone!

If you are "taking more off your husband's plate", what is he doing with that time? Is he just picking the nicer bits like visiting mum and having a cup of tea with her while his sister (is anyone taking things off her plate so that she can concentrate on her mum is doing all the "boring" /practical stuff in addition to her own commitments? If he isn't doing any of that stuff (you don't need a fanny to clean the house) then I can understand her resentment, but it should be directed at your husband, not you.

but the sitting with a cup of tea to chat is way more important than cleaning and way harder to buy. If the Sil agreed to buying in domestic help, they could BOTH be sitting chatting.

Your mother-in-law is absolutely not your responsibility. It sounds like you do a lot more for her than most would do. Just because your sister-in-law is overwhelmed and your husband is unavailable doesn't mean the responsibility of caring for your mother-in-law falls on YOU.

It sounds to me like your mother-in-law needs proper professional care. Because between the care provided by 3 of you (you, your sister-inlaw and your husband) it's STILL not enough...this means it's time to go down the paid care route.

I completely take what you’re saying on board, and perhaps me phrasing it as “admin” wasn’t helpful. As an example, last weekend because SIL had been popping in during the week, I then looked after all four kids for the weekend so that DH could travel to MIL (we live two hours away), where he stayed for the whole weekend to spend time with her and caring for her, sorting things out at the house etc. SIL was then out doing other things over the weekend with friends as DH had taken over.

SIL is with MIL more frequently but DH is more likely to be there for longer periods of time at weekends or when he has time off work. I genuinely don’t know how else it can be organised when one sibling lives 5 mins away on foot and the other lives a two hour drive away? None of us are in a position where we can be taking extended periods of time off work.

That you for elaborating, the picture you are painting is much clearer as to who is doing what. You SIL is in fact doing all the donkey work for almost all of the time, which is the hardest part. The fact that you went and cleaned the whole house and she didn't like the standard would have been the last thing I ever did to appease SIL though in fairness. And I'd gently remind her of that next time she asked what I was prepared to do to 'help out'.

Ultimately there isn't much you can do from where you are, your DH has asked you to take care of things at home the weekends that he is with his mum, so HE needs to be the one having the conversation with her that you are not in a position to physically help, it is too far away for weekdays and the kids need looking after at the weekends when he is away, it's as simple as that, so why isn't he having this conversation with her?

Nearly50omg · 12/09/2026 15:25

Your sister in law is a nasty bitch imo and your husband is not helping or supporting you!! Why didn’t he step in when you planned to clean HIS mother’s house alone and chronically unwell ?? A decent husband would have said no my wife isn’t doing that we will pay for a cleaner if need be!!! Your husband needs to step up for you!! YOU are doing all his household jobs and lokkknf after his mother when he goes to what🤷‍♀️keep her company?? He can set up an iPad for her so he can do FaceTime calls. He doesn’t need to grove 4 hours or stay all the time. He has children who aren’t his wife’s responsibility they are his! Yes you want to support him but they still need time and effort put in by their own father!!!
your husband and his sister need to organise carers to help her. Block your sister in law on your phone. She’s clearly a nasty bully who is just using this opportunity to have another thing to have a go at you with

Yes we are definitely up for organising anything paid for that we can and have suggested cleaners, carers, getting meals delivered and so on. SIL is very insistent that’s not good enough and that it has to be one of us doing it. For example we discussed that whilst MIL was in hospital for a planned spell it would be a great opportunity for her house to be thoroughly cleaned. I offered to organise a professional cleaner to do that. SIL insisted that wasn’t good enough, so on that occasion I organised childcare, did the four hours of driving and cleaned the whole house top to bottom. I was feeling absolutely awful and discovered that evening I actually had Covid. The cleaning I did wasn’t good enough for SIL who sent a rude email to DH about how I hadn’t done things the way she wanted them doing.
I think what this boils down to, as others have said, is that it’s too much for all of us to manage (including SIL) and that something has got to give.

Kindly meant OP, but you sound very vulnerable.

You drove 4 hours round trip to clean your MIL of 5 minutes house because your SIL insisted on it?

Really?

Do you actually believe that is normal.
It really isn't.

Why wasn't your husband cleaning his own mothers house?

You putting your own health at risk to clean the house of a 5 minute MIL.

That is quite extraordinary.
Be careful.
You have children that need you.

You seem very vulnerable to be thinking it is YOUR responsibility to be doing this.

Where is your husband in this?
It's hard not to believe your marriage is a massive convenience for a busy medic.

Free childcare and elder care is a lot for any woman to be providing.
What are you getting from this arrangement is a reasonable question.

Well, she can’t have it both ways. If it ‘has’ to be one of the family that does the cleaning, but when you DO it, she complains, then it needs to be a professional cleaner that does it instead!

Thanks again everyone for your thoughts and comments, it’s been very helpful.

for those of you saying it’s my DH that needs to step up and work out a fair plan with his sister - I agree with you and I will continue to encourage him to do that and hold the fort at home so that he can.

what I was really trying to gauge from this - and which you have helped me with, thank you - was whether I am being reasonable to hold my own boundaries about the amount I am willing to contribute alongside caring for my kids and my own parents and being quite unwell myself. I’m going to carry on being compassionate towards her wherever I can, but hold firm about the amount I am able to support beyond holding the fort at home. If what I am able to contribute isn’t enough for her, I’m afraid she’s just going to have to find a way to accept that.

thank you all!

You are welcome OP the way you have described going forward is the best one.
Wish you well with everything and look after yourself

There is no other relevant side to the story.

OP has her own elderly parents who need additional support. On top of her own children, marriage, job, home and career. She has no obligation to add other people's elderly parents to her list - in this case, her DH's mother. That is his and OP's SIL issue to sort if help is needed and they can/want to do so.

Exactly. Even if the DH isn't doing his share and even if SIL is left doing all the care, none of that is a reason for OP to become MILs carer. Which is the question.

Sure, but obviously I can’t give you that because I’m just me and not my SIL or able to read her mind. But I'm doing my best to understand and make things work, which is why I am here asking for views and advice.

You doing your best to understand and make things work is another way of saying that you're lying on the floor and letting your sister in law walk all over you.
I would have cut her dead the minute she was rude to me. No one has ever treated me like that, why? Because they know I don't take prisoners.

It's clear that you can't do what she expects and what she expects is unreasonable. Decide between you what is reasonable for DH to do on an ongoing basis bearing in mind the impact on you and the rest of the family when he's away. He needs to communicate with SIL what he can and can't do. He should also clearly state that it's unreasonable of her to expect anything of you in relation to MIL's care, as you have your own parents to look after as well as a health condition, and that you have been stepping up at home to enable him to be at MIL's. In addition when you have helped e.g. the cleaning here has been no appreciation from her of your work either. And that any communication around MIL needs to go to him from now on. If she messages you angry messages you can block her.

Pumpkinsaregrowingnicely · 11/09/2026 22:33

I'd start tallying up how many hours dh gives to the care of his dm.
And a list of his other responsibilities.
Get dh to send it weekly to sil.

Yes brilliant idea - that will really help the relationship with his DS - to send her a list of all the ways he is too important and busy to do his share and that she as a mere single woman has nothing better to do.

The person who needs to step up here is the DH. He has two women frustrated with each other, both burning both ends to support his mother whilst he is too big and important to make the time. The sister is unreasonable to say “no” to professional cleaners but we don’t know how her mother feels about it and the sister is the one bearing the brunt of the daily load and emotional stress. If the DM is someone who has never wanted help in the house its the DS who will have to have the daily difficult conversations and many relatives in this situation feel a powerful obligation to “do it all” whilst watching the parent slowly die.

The only person who can really help is the DH - he is the one who needs to step up and get things back to a point where they can have sensible discussions about bringing in paid help for some of the daily care and cleaning. That includes probably putting some other family stuff on hold for the near future.

PetulaGordeno · 12/09/2026 11:50

I am not defending SIL here in her treatment of OP.
But if you’ve ever been the sister and you have a brother/s and they leave you do almost everything in terms of parental care, it can send you to the edges of your sanity where you are just desperate, and I mean desperate for help.
You only have to look on dedicated boards on here.
If you’ve ever think there’s a magic wand and an army of helpers come, forget that notion.
You look at anyone, and I mean anyone around you who may be capable of helping and you become desperate.
Because often appealing to the brother, you get a few noises and a few visits and then ‘important’ things come up.
Not all men are like this I met a few male carers when I was caring but I can tell you this - they were only children.
The fact is OP has enough on her plate already with her own parents, family and health.
Every family I have been around in these situations, these hurtful emotional words can permanently damage relationships. It’s really, really sad.
I don’t have any answers, I wish I did, but the number of times as a carer I have had the darkest thoughts if I had a £1 for each, I’d be a wealthy woman. And it’s very easy to become resentful.

I have a sister in law like. Slightly different scenario but nothing is ever enough despite my husband doing his fair share.
Do not let her tell you what to do, you must put your health and your own family first as I know from experience you and your husband will always be found wanting however much you do.

Grumpyoldcat · 12/09/2026 08:50

Block her. She says she wont talk to you again which is probably a blessing in disguise.

QiBengong · 12/09/2026 08:38

This maybe isnt so much about MILs needs but about SIL- just spitballing here but some of your posts suggest - she feels shes alone, coping with the daily, wants someone to take some of the load and burdens off of her, but perhaps at the same time equates doing these tasks with love and affection, so sees outsourcing them away from family as some sort of failing/betrayal?
There might also be control issues exacerbated by the whole situation of her mothers illness and decline being completely out of her control so shes focusing on what she can take charge of.

She sounds as though she needs help and understanding, but also clear boundaries - eg this is hard for us all, especially for you being there daily for so much - Im doing what I can to support you and especially support DH to do more, but I cant put my job, the kids and my parents on hold to drive for hours and clean to your standards, and I am not sure why you are expecting this.
Keep suggesting outsourcing help with cleaning, laundry and such -'give her permission' to say she cant do it all, and its fine for her to put some of it down.

Does she ask for mental support or destress/talk about emotions when she messages you? or is it all practical stuff?
