Can't blame them. Too many men never grow up, never learn manners, consideration, respect for others' boundaries, empathy, or responsibility. Any woman looking for an adult relationship is likely to be SOL, because most men equipped to handle such a partnership are already in one.
Yes, I know it's not all men who "can't behave like decent people." But it's way too many, and those immature assholes are causing way too many of the smart and healthy women to flee the dating field and tend their own gardens.
We need a better system for helping people get together. Dating--especially as defined by dating apps--is dominated by the players who make up their own rules.
