Men can criticize modern dating. Any gender can. I’m not saying you can’t. The final frame in this comic portrays strong anger at rejection which is never okay. Sadness? Sure. Disappointment? Understandable. Anger? No. The anger signifies that you feel that the other person owes you something.
So your advice is: 1) don’t pay it and 2) work and live in a different country. Super reasonable! /s
