Thanks everyone, ive found this to be one of the most helpful online communities around, mature, respectful and truthful answers.
I don't think seperating is on the cards. But perhaps id be silly to rule it out. We've dealt with past problems. The issue is this time it's just reoccurring problems.
Things I've told her over and over not to do. Another example just so you get my angle.. I have a 'mancave'... just an office kinda thing off the side of my garage. A place that I like to keep my things like my collectables, got a pc, tv/ps4 out there too. It's understood that this is dad's room, ive tried to tell her that she's not to touch anything in there, and it's my responsibility to keep it clean. Yet time after time she comes in and 'cleans'. Why does this annoy me? Mostly cause she throws things away, what she thought was rubbish may be a reciept I needed to keep, or something I was fixing. I half think this is just a reason for going through my stuff.
Sorry for the spelling mistakes too, I'm at work trying to do too many things and not proof reading lol
