I can certainly relate. I spent 12 years with (and had 3 children with) a man child, and it was, as you described, hell! I did everything, literally everything. He didn't even work for the majority of the time we were together because he was content to accept family money. It was pretty clear that his failure to grow up stemmed from over parenting on the part of his mother and grandmother. He's now a part of my distant past, but because we have children together, I still have knowledge about his life, and surprise, surprise, he's 51 and still functioning as if he's about 14.
