I recalled something someone had said about why he wanted a divorce, how it was because he preferred to absorb the pain of living within himself rather than inflict that pain onto someone else. I don't remember exactly how it is worded. "Inflicting pain on another that we would inflict on ourselves if we were alone."
Something along those lines.
It was from the science fiction film, Altered States which I saw in a theater many years ago as a teenager when it first came out. I used to watch it with potential girlfriends to let them know what they were getting themselves into.
It was a pretty deep thing he said though. I don't want to blame everything on a woman, and I don't want her blaming me for the general wretchedness of life which neither of us would be able to change.
