I'm sorry you're hurting, but it will get better. A word to the wise, though. If you have children and they are minors, you have every right to see them on a regular basis or even have joint custody. I know of many ex and exiting jws that don't feel worthy of raising their children. If this is your situation, please don't make that mistake.
And as far as your wife leaving is concerned...she's never going to be good for you unless she changes her brainwashed state. Look man, I'm sure you didn't stop being a jw so you could become a Hell's Angel. She has to know that there are things about the WT that bother your conscience. If that's not good enough for her, then she's not good enough for you. The same goes for parents, siblings and any other family members.
