Conserve cursor X position when moving cursor up and down

[freiguy1]

For example, I'm editing this text

A sort of long line^
Short
A really really really really really long line

Imagine the ^ is my cursor position. When I press j to navigate down one line, the cursor correctly goes to the Short line and is at the end of the text for that line. When I hit j again, The cursor drops straight below where it currently is. This behavior is incorrect. It should conserve the initial X position in the first line, so when navigating to the bottom line it should appear somewhere in the middle (of course I could figure out where exactly if I were to count characters, but I don't think that's necessary).

Could this be some configuration I have setup incorrectly?
Thanks!

I assume you have j mapped to gj?

Yessir.
