Bollocks. It's a nice fairy tale he told you, but nah. All the time I was online dating in my late 20s, my messages were all from men in their 40s and 50s whose profiles clearly stated they weren't open to dating anyone over 29. Despite MY profile saying I categorically wasn't interested in dating men old enough to be my father.

They just don't want a woman mature enough to challenge them on their shitty behaviour.
