I wouldn't be supporting anyone who gave up their job without having another one to go to. It would be a dealbreaker for me. It's highly irresponsible, and incredibly selfish.
And 'coding'... ? Why does he think this will be any less stressful than his current career? As a few people have said, the grass is rarely greener on the other side.
Like some others have said, I also know/have known quite a few people like this... Always wanting the next best thing, the next best gadget, a better car, a better mobile phone, a better/bigger house, a better TV, a better stereo, and always a better job etc etc etc......
And in some cases, they have spent a substantial amount of family money, (and even got the family in debt,) with all sorts of daft 'new ventures...'
And every single person I have ever known, who is like this, is a MAN. Always a man. Most women seem fairly happy with what they have, and even those who aren't, will try and better themselves without affecting anyone else. But men seem to always want more, bigger, better, newer; and to hell with everyone else, and how they might be affected by it.
As I say, I know/have known a few men like this, and I seriously pity the women who have to put up with them. I have seen women at their wits end with men like this, and trying to juggle the finances to pay for everything, or support his new venture, and/or constant 'career' changes...
I simply couldn't be doing with this. I'd be out of that relationship!
