Its gotten worse because women are no longer forced to stay in or get into shitty, unfulfilling marriages. Men before had guaranteed companionship in the sense that it was societally and financially expected for a woman to stay in a relationship and provide emotional (and physical) companionship. With women becoming more independent, they’re able to leave abusive situations or to avoid getting into them in the first place.

Therefore, if men are not socialized to maintain friendships and no one is being forced to emotionally support them anymore, then they are lonely.
