I was in a similar situation; while I can't blame it all on my job, but it was the complacency that got me. I ended up separated from my wife and seeing my kids only a few days a week. When you feel like that do something about it. But speak to your family, prepare them for a while where they will have to live financially reduced and then make a change. Change is the first order of the universe, resistance to it will bite you in the end; embrace it and ride the wave instead.
