Name change.
DM lives with me and two of my children (11 & 15) since my dad died four years ago.
When we moved into current house, she refused to live in the annex as intended and as such I have been in there, with DM in the ‘main house’ with bedroom near to DCs.
She has become progressively intrusive on our lives - constantly talking, humming and singing around the house, banging doors closed instead of using door handles, has a happy dog that she will not train and believes she has every right to walk into whoever’s room she pleases on the pretext of ‘gathering laundry’ or ‘making beds’.
I have said all along that the DCs bedrooms and mine are our private spaces, and told the DC that they were responsible for tidying their space, putting out their laundry / dirty crockery, etc. They’re pretty good - not 100%, but not bad.
That hasn’t been good enough for DM , though, who has carried on helping herself, taking it upon herself to pick through their things ‘tidying up’ and has caused minor damage to DCs things at times through carelessness.
Having had enough, I told my DM of my plan to install fingerprint locking handles to mine as my DCs rooms, and have bought some hanging ‘do not disturb’ signs for use when DCs want time to themselves or when I am trying to work from home.
DM has hit the roof, saying that I am being rude and making her feel like ‘some sort of criminal’
AIBU?
