i used to work in IT consultancy in HR role. The divorce rate amoungst the mobile consultants was very high - they got used to the bachelor lifestyle during the week. Down the pub. plenty of cash to splash. Dinner out. there were a lot of shennanigans amoungst the consultants on client site...many an affair.
WHen DH's came home of a weekend, they wanted domestic bliss, honeymoon sex, pipe and slippers and freshly scrubbed well behaved kids. ANd lie ins! The wives, having been trapped at home all week, wanted to go out on the town. To have 5 minutes peace. to have a life. INstead, they would have to organise laundry, family visits etc etc.
If you have supportive family nearby that can help with the kids, I think that its more workable.
However, I was at home working wifey for years while kids were small. (DH worked abroad 10 days, home 4). No family nearby. The stress was immense - everything falls on you to organise.
Kids sick...you take time off work to take care of them. By end of the year, DH has 3 weeks leave to take, and you have no time left as you have used it all on sick kids and dentist appointments and school plays and organising the day to day stuff of family life.
DH would come home exhausted and would try to "manage" the household. How he thought I did it all week without is supervisory skills, I'll never know!
we all felt we were in competition to get his attentions - kids, me, dog, his folks.
It really isn't easy, and the money, while handy, does not compensate for the lack of support and companionship.
For example, one snowy night, around 10:30pm DS had an asthma attack - I had to wake the other two kids, load them to the car, (find some screen wash for the wipers), drive to hospital, deal with three exhausted kids in the waiting room, one of whom was struggling to breathe, bring them all home 3 hours later....NIGHTMARE. And then explain to work why I couldn't come in because kids were shattered and couldn't go to school.
think carefully about your own carer, your needs, and how much support you can get from family.
