I wanted kids. I got a great baby boy. He doesn't cry much and he is really smart. The smelly diapers suck... but she changes way more than me, and those don't last forever anyway.
I love going home to my wife. She is a great woman, is beautiful and is highly intelligent. We have a lot of fun and never really fight. We have some quiet times where we don't speak to eachother, but never does it get into a yelling match.
I have had roommates that I fought with tremendously.
All in all, I wouldn't trade it for being single for the world. Of course, I waited until I was in my mid twenties to get married. I think many people start too soon.
