Your mum had 8 kids and that will make any house messy.
Get on top of the house gradually.
We renovated when my kids were small for ... 10 years ... so there was never the whole house looking sparkling clean I can tell you. I came across maggots twice ... eeeekkk wake up call ... but ... only to clean the maggots, not to diss your own character or your mother's cleaning.
... when kids are little ... you have not got time to worry about anything but the essentials. You owe yourself the best care possible as your mother was obviously not able to spare much energy for you alone, which is why you admired the hubbies family. I had a more opposite families attract dynamic hoing on ... rather than opposite people attract. On the surface of it all ... his seemed more kind, friendly, successful, beautiful, educated ... you probably know the scene.
After 5 years with ... hub .. I was screaming inside ... that even tho I grew up in "a ghetto" as hub called it ... we had clean walls ... and approximate order... and actually cared for each other ... not on the superficial ,, if I can throw an overseas trip and holiday into the bargain ... I will visit. etc ... Different worlds ... we cant fix our families ... just be kind to YOU.
Separate out the role of mothering and cleaning ... they are interrelated ... but not everything ... honour your own style ... even if it overlaps a little with less desitable aspects of your mother ...you will be different ... as a whole person ... for sure.
There was a book "My Mother, My Self" ,,, it helped me. Also "Woman Time".
