Possibly the most disturbing thing about women that I've learned is how some of them are such psychopaths they don't think there are any worthwhile single men out their in their dating pool so their conclusion is that they have to go and slip into a relationship. To the point they'll try and make friends with the woman in order to steal the guy and ruin the relationship itself.

Pre-selection in action. Women prefer men who have been selected by other women. This is why middle aged divorced men have better outcomes in online dating compared to their long term single male peers. It's also why you hear men say that the second they found a girlfriend, they suddenly got attention from other women. It's why the top percentile of men have options while a significant proportion of men are treated as ghosts. And why it is impossible for a woman to be involuntary celibate.
