SolidGold, Cretaceous, Helltheno and others who've suggested it- the anger theory makes sense on paper, but it's a very long time to hold a grudge. I suspect it's a whole lot more intrictate.
Tbh, I do recall periods over recent years when I have tried very very hard to be interested in her work, but could not longer do it. That makes me sound horrible, but what I'm saying is that I just couldn't understand what she actually did anymore, and I had to pinch myself hard to stay concentrating when she was talking about it.
Meanwhile, I was taking on increasing childcare responsbilities at home on top of my work - simply because I was freelance and not regularly tied to commuting hours - which I began to feel she was taking for granted. When, after several years, I tried to get her to see just how much I was doing and how it had started to delimit my work choices, she was furious and said she didn't give a flying fuck about her work and would swap roles instantly.
This came as a massive shock and surprise as I had helped her to nurture an ambition to become senior in her field, as she had always told me that she wanted this. How could I get this so wrong? But more to the point, what else could we have done? We both needed to work to sustain our massive mortgage and overheads, and flipping round the other way was not an option. There was/ little opportunity for freelance work in her sector, and she told me that as a personality, she would not be able to deal with the intense isolation that I sometimes experienced.
I started to feel defensive, feeling that maybe I should go back to a super-traditional model and launch myself back into a corporate job, but she/we had no strategy that would make this possible.The hours in my sector are notoriously long. She didn't want a live-in nanny, she did concede that I was doing a great job with the children, and by now, I had become reluctant to relinquish control of an area that I had dealt with for many years.
She also seemed to enjoy the status and was justifiably proud of her achievement. But these dynamics were unsustainable. I was starting to feel as if I was losing out on real work opportunities- well, I was. At a practical level, getting so bogged-down with the school run and activities that I couldn't complete my work except by staying up until midnight or beyond.
One boxing day, I got up at 4.30 to start a piece of work and pretty much worked solidly until 12 hours later. You can imagine what sort of Christmas that was.
I'm clutching at straws here now. I need to write her that letter, and I need to do it before our next therapy session. Only she will be able to shed light on why things are as they are, but first, I need to ask the right questions - and some that are very direct.
