Take some time to think about this:

> I've worked hard. I haven't had a vacation or day off in years. (...) My life is wake up, code, sleep.

> When she's done with her day, she goes to play cards with her other friends.

In order of importance, I feel that that you would benefit the most from speaking to your wife, a psychiatrist, a marriage counselor and possibly a lawyer.

Not knowing you personally it is difficult to ascertain your mental state but if your writeup is any indication, you really, really need some time off; not a new startup.
