So she set you free and now you can plow other women and you are upset by that?
I realize that it may have been a shock, but wasn't it time for it to be over? Were you completely happy?
Maybe she pissed you off all the fucking time. Maybe you are better off now.
You can't see it right now because you are sad and hurt that she heartlessly discarded you, but in a few years you will probably see that you dodged a bullet
when i was a young man, i felt like you do now. a couple of times. and now, ten years later, i see that it's true that a man's value just keeps going up. because now, the women are hotter, younger, more fun, less problems, than the women that i met and could date when i was young.
you will have more and more options as time goes on and as you mature as a man. but your female friends will experience the opposite, and this girl may one day very much regret her decision to dump you one
