I agree with Nexus. Now I don't blame you for going thru her $hit, we're all human, we all have emotions, and sometimes they rule us. But the more mature you grow, the more you can rule your emotions instead of being ruled by them.
But here's the thing~ an alpha dog doesn't care if some B!tch has contact with another dude, I mean, so what? Dude all women are sluts, they all str8 are, either they're open about it, or they hide it, but they all are.
Except the full sexual repressive tight a$s Christian girls. You wanna date a Christian girl? No. So chillax on the jealousy and forget about her seeing another guy.
DUde you're only 21 or something. No WAY you should be exclusive with some slut. You should always be looking to acquire more plates, coz you know for a fact that all woment have no loyalty.
I believe that women used to have loyalty, but for the last 30 odd years, women have been culturally programmed by the feminist media and academia to believe that their value is so much higher than men's. Therefore, when they automatically feel their value is so much higher than what it objectively is, it is just in their nature to be less inclined and more reluctant to "settle" with just one guy.
It is a great shame that our fathers let society become like this, and allowed the insidious influence of feminism to eat away the base of our masculine power, but $hit I ain't gonna cry about. Neither should you. Just accept the new reality~ there is no commitment anymore, law of the jungle dude. You must take want you want, and keep taking, keep seducing, keep gaming, new chicks new girls everyday new girls.
Shoot dude, you're rich, why you let some broad affect you emotionally so bad? She didn't "wrong" you, she was just doing what society has conditioned her to do, to be like. Accept the new reality dude, don't hate the player(ette), hate the game.
