Sometimes I do. I try to do actual work, so I'm bringing in SOME money, but my health doesn't allow me to do much. And Jos is so good about it. He keeps saying to me 'even if you never succeed, you were brave enough to try. And you're happy. I love you, that's what matters to me.'
So yeah, I feel guilty over it, like I'm living off him or something.
But that's not what it is. If the situations were reversed, I'd do the same. If you're lucky enough to be able to afford to do this, and your wife is OK with it, and the writing doesn't hit into family time, you have nothing to feel guilty about.
