@ceo_of_monoeye_dating She uses the term "scrote," which tells us she is a man hater by default. The female equivalent of the guy that uses the term "foid."
Not surprising he was not interested, as he could probably sense that she was the exact kind of woman who would be nothing but a bitch to deal with.
That said, I don't think he was lying. A man with enough going for him that the rejected woman isn't downplaying him is probably actually a quality man. He could have a woman if he wanted. The fact that he was available probably means he's disinterested in women in general.
