After 7 years of living together I finally snapped this last few months. Everything just became too much.
I have and had been carrying the mental load for everything. Housework, sorting holidays or any days out, appointments, birthdays, anniversaries, have I seen his glasses/keys/phone because he misplaced them for the 100th time, what gifts he could get me because he didn't know so can I think of something...
Only advice I can offer is let him deal with the consequences.
In my case laundry was a big issue. I would put a load in the washing machine before work and all I would ask him is can you hang the clothes when it's done. I would come back and guess what clothes still in the machine or if I had hang them to dry I would ask him if he can fold and put away. Again I would come back from work and no change to said clothes. My solution? I stopped washing anything of his. I bought a seperate basket, put all his clothes in it. He knew of its existence and that it was his basket and his responsibility. Two weeks later he came to me complaining that he couldn't find any of his trousers and have I seen them anywhere. I just stood there smiling. It eventually dawned on him that they were all where he put them in his very own special basket. He pretty quickly learned how to operate the ''so complex'' new washing machine that was "too much" to handle before.
I also stopped knowing where everything is.
'Have you seen my keys'
'Nope'
'But you always know where everything is...'
'Nope'
Now guess what, he seems to have become an expert in finding things!
A few months ago GP put him on permanent medication. I declared from the start I wouldn't be reminding him to take them, order them, book review appointments or anything related to them. He could sort reminders on his phone.
I also stopped reminding him of important dates. As a result he forgot our anniversary this year and why oh why I didn't tell him in advance, I know he struggles with dates afterall! Poor lamb... Tables quickly turned when I pointed out he has a phone with a calendar he could have used to put a reminder on.
After that I have reached a stage where I don't care anymore about anything and he can see it. Ironically that seems to have put the fear in him as I now come home from work and things are tidier and he seems more organised and in control. Unfortunately, I feel detached and too little too late by this point.
