If your seventy year old mil is nasty and selfish enough to not want to give up every spare hour of her retirement to provide free full time childcare for her precious gcs who live seventy miles away, which would involve her getting up at five in the morning five days a week, so she can be there to provide breakfast, dress them, get them ready for school and drive them there every morning, then she cleary is a lazy, selfish bitch who hates her grandchildren and you should immediately go no contact and block her from ever seeing them again. (Apart from the times when you need her to look after your house when you are on holiday - on those occasions she is allowed to have a key to your house so she can come in and look after your dog, but when you return from holiday, the key must be returned to you and no contact will be resumed.)
If you can't drive, then you are an inferior human being who does not even deserve to be regarded as a functional adult. What is wrong with you? Why are so lazy, immature and useless that you haven't even bothered your lazy, selfish arse to learn to drive? You are a burden on society, and if you dare to have the audacity to ask for a lift back from a place to somewhere the driver is going anyway, you are a cf who should be dumped at a remote bus stop at eleven o'clock at night in the freezing cold when there isn't another bus service for at least two hours to teach you a lesson.
If your dm is in your house and, heaven forbid, she does the dishes for you without your permission, or puts a fork in the wrong section of your cutlery drawer then you should go through her like a dose of salts! She is clearly being difficult and controlling. Monitor the situation for further red flags and be prepared to go no contact.
If your dh does something that you amusingly find irritating and share on mn, then it's pretty clear "You don't really like your husband, do you?"
If you are claiming benefits of any kind, for any reason, you are a lazy geedy bitch who is a drain on society. If you brag on mn that your are earning £100k plus in a job where you don't actually do any work, you are applauded for not telling your manager you contibute nothing to the company.
If your dh is out three nights a week sleeping on a female work 'colleague's "sofa" because she needs emotional support, while sharing clandestine whatsapp messages with her about how unhappy he is with his sex life, you are insecure, paranoid and controlling. All the cool wives are fine with their dhs being out seven nights a week with their "work wives". What's the problem?
If your dh dares to fall asleep at a time you deem inapropriate it is a serious red flag. He has obviously checked out of the marriage and you should get your ducks in a row and ltb.
