I have stay with MIL TO BE at the moment and it's not going too well.
She treats my partner like he's still seven. Shouting him to 'have a word' over something silly or just being niggly and annoying.
We do our own shopping, we have our own freezer there but have to share fridges. She keeps eating our food, saying 'there's not point me buying any if that's there'. We're on a really tight budget at the moment, especially because we're paying her 300 a month for the pleasure of sleeping in her box room, so our food budget is limited as it is!
She borrows our car, uses all the petrol, and then puts it back on the drive like she's never even used it.
She complains if we're in the shower for over 5 minutes
She stops up late all night shouting and laughing well into the early hours, but then complains when we're getting up early for work in the morning and happen to make too much noise whispering.
She also does the thing where she shouts my partner, when he replies she ignores him so he then has to go to her... Only for her then to say 'oh I've forgot now!' not in a oh dear I'm forgetful way, but in a HA HA way.
It sounds like I'm being really petty... Am I??? I dont know!
