He does. He knows that void well and he's tried to fill it with sex, alcohol, poorly chosen relationship partners, Iron Man -- all of it. Because it's better than nothing, or at least, that's what you always tell yourself, isn't it. This is better -- a better feeling -- than the other one.
But that void, that being unloved, it's a pit dug in sand and each time you put something in it, the walls fall away a bit more, it gets just a little bit larger. Colder. Harder to fill.
