Background: 3 years ago, we moved into an absolute dump of a house. Everything needed doing. Plastering, windows, doors, decor. We decorated the DCs room to a habitable level.
2 years ago, it was time to start making the rooms 'proper bedrooms'. We spent £2500ish on DD11 and DD4 (at the time) bedroom. Carpet, plastering, decorated to DD11 choice, bunk beds, wardrobe, drawers, curtains etc etc.
Within 2 months, drawers had broken backs from DD forcing too much in, room was full of rubbish, impossible to walk through.
Fast forward 2 years of me lecturing them, 'put clothes away, clear the floor, get rid of empty glasses etc, show some respect'
DDnow13 came down tonight crying hysterically because she'd torn the (expensive) wallpaper.
My response was 'I'm past caring. You have no respect for your space, forcing your 6yo sister to live the same way. The bedroom will stay the way it is permanently'
She's now sobbing about how I'm angry with her (I'm past that) and disappointed in her (I was but genuinely past caring) and how she's going to save to redecorate (not happening as the rest of the house needs to be done.
So not to drip feed, this is the main bedroom of the house. Myself and DP only got carpet in our room 6 months ago, no decoration or furniture other than the bed we sleep in. Other DCs have adequate decor and carpet but need upgrading.
WIBU to tell her to I don't care about her room anymore?
