Now that's a story, Freaker.
Sorry to hear about your "dark" thirties.
Whatever happened with your marriage?
Isn't it amazing what people do for a relationship?
It's stories like yours that make me reluctant to settle down.
Women.

What can you do?  Marriage is a commitment, and we take the good with the bad.  There was no way of knowing postpartum depression would ever be a factor, unfortunately, until we had our first child.  
My daughter had very severe colic, and those times were just awful.  Non-stop screaming up to 18 hours per day.  We were sleeping 1-2 hours per night for almost a year.  I also failed to recognize it for what it was--why 
wouldn't she be depressed?  But it was a side of her I'd never seen before, and I seemed to handle it alot better.  It wasn't until we had our second (and last!) that it became clear.  He didn't have colic, slept through the night--the perfect baby.  But my wife was even 10x worse.  At points even floridly psychotic, to the point where I was actually terrified to leave the house for work in the morning or in the middle of the night because I feared she would hurt them or herself.  
But this time I got her right to a good psychiatrist, and we got it under control, and then she just slowly got better and better, but it took time.  I must say, that now things really are just great.  My wife is truly my soul mate, and I couldn't imagine going through life without her.
but, yes, marriage is not easy, and it's no fairytale for sure.  It takes a tremendous amount of work and sacrifice.  Same with being a dad.  It's just not about you anymore.
Except when you descend those stairs back down to the gym...
