Most Helpful Girl
Most Helpful Guy
I know that obviously has to hurt, but if you think about it objectively you just dodged a fucking bullet. From my perspective she threw away a possible relationship just to hook up with a random guy she just met at a bar, and let's face it those situations rarely translate into healthy and good relationships.
You should be thinking that she is the one who fucked up, you gotta have enough self worth where you think you're a great guy and that you're gonna make a great partner for some girl you really like.
But you're ruining this for yourself with your shitty attitude of "women are not for me". There are plenty of women who see things just like you do and just want a caring loyal relationship with an amazing person. It could be that you're going after the wrong type of girls if you've never experienced that.
