My love for my daughter and my wife enrich my life and contribute more to my happiness than anything else, by far. As you wrote, the majority of the very, very hard work has fallen to my wife. I wouldn't fault any woman, or man, for not wanting it.
Still, my wife and I both feel that parenting is the best thing we've ever done or will ever do. It's everything I hoped it would be -- and much more besides. The benefits are innumerable for us.
Honestly that's fantastic and I'm glad it turned out that way for you. The world needs parents who actually raise their kids and want to.
I only encourage people to do the requisite research to make sure they make the right choice for themselves, because for many it's not.
