Money is not everything. You don't know if you are dead tomorrow. You don't know if you live the next 5, 10, 20, 50 years (I wish you all the best for a long healthy life). You simply don't know if you become sick or not. Ignoring resurrection, you live now and will die afterwards. There is no magic around it. It is a fact.
Even at the time of your death, when your wife sits next to your bed, you will die alone. Nobody can go with you this last step. When you understood that you die alone, you can make your decisions.
What do you want to do with your life?
Nobody can tell you.
I just know one thing for sure: money makes you well fed, but not necessary happy. You can live poor and happy. You can live rich and unhappy.
What makes you happy?
Do you want that your children can raise with their mom onsite? Then you need to do the according job.
Do you want to make career? Ask you, for whom are you doing that? What is the final outcome? Should people say:"this was a hardworking man, until he got the heart attack. Well, no lets hear the applicant".
There is nothing you really need to reach. Probably you just need to live. While your boss will thank you for the hard work, he will fire you the next day when you have a burn out. If you read a story each night for your kids, your kids will remind this even when they are aged themselves.
Your question is not easy to answer.
I left my well paid job to create my startup with no income (at the moment - hope to change later :-)). I have no idea abou the future. But I can work in my own office and every lunch I meet my wife. When there is something wrong with the horses I can go off in the middle of the day looking for them. Nobody can pay me that in dollars.
When my startup doesn't work out, I will do something else. I guess you will find another job again if the huge company is not to your liking anymore. We are never speaking of "for ever". Lets speak about "now".
So, the answer is: you must know it of your own. You are for sure not insane. Others (like me) did something similar. Everybody thought I am insane because i left the company. But who care what "everybody" is thinking?
I can recommend you the following: sit down, shut up and think about what would YOU do when you can freely decide. I mean independent from your wife, work, rest of the family. Then you know what you want.
And if that doesn't help, I can recommend you some books about Zen ;-)
Long story - I hope it didn't bore you to much and is finally of a bit help. Good luck!
PS: some ancient asian wise man said: you must make a decision within breathing 7 times (freely translated). I always thought this is a pretty fine rule.
