Hello there. I read your situation and I can try to help you understand your wife's need to work.
Working provides many important things for her. For one thing, it provides a paycheck that she earns herself which gives her some freedom, independence and autonomy. Your post shows that you tend to have the "final" say ("I told her NO!") She's not a child.
I need to explain something important, too. When she was younger, she might have felt perfectly fine as she accommodated your needs and the needs of your children. But now that she is older, she no longer has the flood of estrogen that helps her brain become more nurturing and pleasing for others. Now is the time for her own actualization. If you force the issue, she will rebel.
How nice that you're offering her all the perks of financial security and travel. But working still gives her a sense of independence from you. It's her money and she doesn't need your approval to spend it. She may also enjoy the respect from her co-workers. It's different from her relationship with you.
Here is how you can help:
1. Let her work. If you don't make it a problem, sooner or later she'll come around to see that her schedule gets in the way of enjoying travel time with you. But let it be her decision. It won't last for long if you don't press the issue.
2. If you have the financial resources, hire a housekeeper or house cleaner to take care of the things she doesn't have time for.
3. Be pleasant to be around. Make her want to spend time with you!
4. Provide plenty of social connections so she doesn't need them from the office workers.
Do you treat her differently when she stays home full-time? Do you expect her to be the housekeeper? Cleaning sure isn't very fulfilling.
My husband loves to keep me at home. I was barefoot and pregnant from the start. I went back to work several times with fantastic career opportunities but he made it difficult so I ended up quitting. I don't blame him, but I did miss the independence and my own paychecks. It's a great world out there and I wanted to be a part of it. He kept me in a nice comfortable cage. He still does prefer that he is my main focus but I'm working out of the house currently and it's enough for now.
You must not stifle her! Be patient. I can't think of a single working woman who wouldn't give up her job to travel with her husband!!! Your wife will come around when it is HER choice to leave.
Until then, if you want to travel and she can't or refuses, find a relative or a buddy. That should make her think twice about being left out of the fun.
