Her bedroom is a pit. I’ve cleaned and tidied it regularly in the past, but she just makes it so filthy within days. Littering with bits of paper, clean laundry strewn over the floor with the dirty (despite having perfectly good places to put both), broken make up etc. It’s a pit and I hate it but we’re at a stand off, she knows I won’t let it stay that way as it’s vile so won’t tidy it. I work long hours and barely have time to keep on top of the house as it is. AIBU to just shut the door on it , stop doing her washing etc and leave it to fester until she either sees sense or moves out and goes to uni (which is years away).
