We were OK in the beginning. We were OK when the DC came along. We had a System that worked. I did the laundry, he did the cleaning. We did the shopping together. He put out the bins, cleaned the toilets, mowed the lawns and took the cars to the garage. I did the paperwork, managed the finances and the insurances and paid the bills. We worked around the DC so there was always one of us there.
Then they were teens and they would unpack the shopping, load the dishwasher etc. Suddenly anything not done and it was "the boys were supposed to do that" and I didn't notice that DH was doing less and less and less. He was still cleaning the toilets, running the vacuum round the lounge and putting the bins out at that point.
Then we had a bonus baby and I had 9 months off on Maternity leave. I suspect that's where it started to go wrong. A couple of years later we had to relocate for my job and that's definitely when everything collapsed.
We've been in this house nearly 10 years and I can count on one hand how many times he's cleaned the toilet. He was moaning once that "nobody puts the bins out" and was quite shocked when I replied "that's because it's your job". He's stopped moaning but manages to "forget" on fortnightly bin day and doesn't put the bins out.
He moans that I don't put the shopping away but doesn't see that I am the only one meal planning, shopping and cooking most of the time.
I had cancer a year after we moved and just dropped everything. Thought that if he couldn't be bothered I'd play him at his own game. We went seriously overdrawn, bills didn't get paid. The house descended into the sort of tip that takes several people months to sort out and has never recovered. He "tidied up" by putting everything in boxes. We have stacks of boxes in every room. I have no idea what is in them.
Unfortunately when he tidies he just puts everything in the box, so there will be important documents we've been looking for, newspapers, crisp packets, odd socks, tea towels, books, probably china, photos, pens, cheque books, hairbrushes, DVDs all mixed together in each box. You can't say this is the box of newspapers so I'll just throw it out. I tried that once and mixed in with the newspapers was the folder with all the original copies of DD's birth certificates in. Lucky I checked it. I'd really rather he just left it all where it was. It's so much easier to tidy as you go rather than ending up with a stack of boxes to check.
