I think everybody goes through bad spells. I think my wife and I are in one right now, but neither wants to say anything. This one seems to be longer than other spells, though.
I know part of it is my fault.... I used to make $80,000 a year, and was laid off 3.5 years ago. My wife wanted me to stay at home because she made even more money than I did, and she wanted me to basically raise our kids, which was fine for me. My wife was in a really stressful job, and it was nice to see my kids ( I used to work nights and barely saw my kids ). Then she took a new job for slightly less money, but with less stress, and closer to home. And she has a boss who really appreciates her. Life is good for her right now..... EXCEPT I think she hates me making so little money these days. The pressure is on her financially, for the most part.
That said, I consider my job these days to be managing our money. Turns out that I have been rather lucky with the stock market... But whatever money I make by investing, is almost like it is invisible.... we never use it, and my wife has no idea how much money we actually have in stocks.
I'm 50 years old with health issues, tho by and large I feel pretty darn good. But I spent 1/2 my life working in TV and Radio before getting laid off. And the older I get the less I can put up with BS from "kids"..... In TV I had my fill of clueless recent college grads who really had no clue about TV, who were given "titles", in lieu of money. They thought that meant something.... Well it might have if I didn't have 20+ years of experience compared to their 1 - 3 years of experience..... Point being that I don't tolerate nonsense well, nor do I tolerate idiotic people well. I have a pension for saying what I think.... That would have had me in lots of trouble had I not been in a union. So, I don't feel like I can work for idiots again; without union protection I would only end up getting fired.
All of that said, I really want to open my own FT business. I own a PT DJ business, but I don't make enough money from that to really make a difference in our lives.... basically I use that money to pay for our vacation every year.
The business I want to own would legitimately cost about $100K to start properly, and being 50 years old with 2 11 year old girls makes me very hesitant to risk that much money on a risky new business.
I guess the point of all this rambling is that there is always some issue or issues that keep us from being the same as when we were newly married, with no kids, with tons of cash, and no health issues to worry about. Stress, no doubt, leads to lots of problems.
I wish you good luck, and just would like to say that you should look before you leap.... the grass sometimes just appears greener than it is.
