I need to continue my work in some way though (even if it’s fewer hours and demands) as it’s a huge part of my identity and does real good. DW will support any choice, but reckons if I stopped work I’d be a terrible, frustrated tennis club wife, and would probably end up glued to a Tube train, or something (maybe!)
We have 3 kids and DH and I were both equity partners at city law firms (US equivalent). I was actually ahead of him as he did something else before retraining and so was made partner before he was. We did make it work through absolutely rigid timetabling, a nanny (two nannies for some periods of time), a housekeeper etc. We both left the office as early as possible whenever possible even if it meant bringing work home, opted out of almost all business development unless it could seamlessly combine with a necessary trip, juggled every emergency/illness depending on who was under less stress, etc. But truthfully it was a constant, exhausting juggling act. Honestly, there were months where our travel schedules meant we hardly saw each other.
When he was offered an opportunity involving an international move that we were all excited about, we decided that I would take some time off while we got settled. I haven't gone back and, to my surprise, haven't regretted it at all. It just felt like taking a giant, deep cleansing breath. Our life suddenly felt relaxed and enjoyable rather than something to be managed into submission.
I unexpectedly found so much to do with myself I've never looked back. I spent loads of time with the kids, got involved with the school and from there, school governance. I was able to use my legal background in a voluntary capacity to help a non-profit org (which ultimately led to a job, but a much lower key one), sit on boards as a trustee, went back for an MA degree, learned a language, got a culinary certification, became involved with a therapy dog organisation, did a few consulting jobs, did some writing and got published. We also kept the housekeeper and gardener as I was not particularly interested in spending my time on cleaning, laundry and gardening.
Anyway, my main point, is that as long as you're willing to do some serious thinking about whether you can reframe your definition of what makes you feel successful/fulfilled etc., stepping back doesn't have to sentence you to a lifetime of tennis club - I'd rather cut off my own arm. I did have to look long and hard at how much of my self-worth was tied up in professional success and financial reward. If you can see a happy future taking a different or lesser path, at least for a while, then try it. If you can't (and there's nothing at all wrong with that) you absolutely shouldn't do it or you'll end up resentful and unhappy.
