A former friend of mine at uni became obsessed with a girl who worked there, and started to develop all sorts of creepy behavior towards her (watching her for hours on end, stalking her home down quiet country lanes, found out where she lived, etc). All without ever trying to talk with her or ask her out. He became fixated with her, and of course she noticed his obsession and became uncomfortable and started to stress out.

At one point I told him that his behavior wasn't cool, and that he should either ask her out and live with the consequences or move on.

He got really angry at me, which didn't surprise me. But one of the things he said to me was that I didn't understand women and that's why I was and would always be single. It was honestly funny because he was also single at that time.

Roll on the years and I've been happily married for a couple of decades. And from what I've been told through mutual acquaintances he's still single. And probably still stalking women.

This meme reminded me of him.
