That was obviously intentionally hurtful, but unlike so many others, she was at least being honest. She could have been honest and not a cunt about it, but the cruelty was obviously the point with her. Even considering she ended the relationship, it was best you moved on anyway.
This video is funny, but its very possible at least some of those guys - here and other cuck videos - are growers with a large difference between totally flaccid and totally hard. The funniest ones are with guys that have at least a decent sized cock when hard, and the woman is treating him as if she needs a tweezer to find it. Lol.
