Dude! Slow down lol. Im sorry to laugh because I know how you feel and shit but you need to stop like right fucking now!
Do what the guys are telling you.
I been in your shoes and you know what? I got needy and in the end I don't have the girl. This is the way I see it..... Eh herm! Right now you are pretty much what we in the industry like to call SOL. So! Do what the dudes are telling you and if at the end of the day you still not with her anymore then guess what you really didnt loose anything because you never had her... Sort of. It makes sense in my head.
One thing you will have that I didnt in my younger years is knowledge and your manhood. When I think about this behavior that I myself displayed many times and wondered why the girl would leave me or never came back, I think of the movie Hitch and he runs to the car screaming why, and the dude tells him dude you are doing it right now as in this is why she doesnt want you.
Bet! Takes this for a spin. Dont say shit to her for say ummmm 2 weeks. I bet you a gigagillion bucks she will in some way shape or form try and connect with you. Dont add her to your facebook. You deleted that shit and if you add her it shows you are being needy and man enough to hold your ground. She will facebook stalk you. Thats a guarantee because facebook is like cocaine/heroin/crack/and weed all rolled up into one for women and they fucking loveeeeeeeeeeeee to facebook stalk their exes for either self validation or other shit. Why you think majority of women specially younger ones have like thousands of friends on fb? So in other words dont add her. She will will look you up. Instead pimp your shit. Update pics, go out. Show you are happy and not faced by this.
She will reconnect and who knows maybe you will have a chance again bit don be surprised that after you go out there in the field of battle(streets,clubs , whatever) you might find that you are happier and dont need her.
Your other option is to continue being needy and completely fuck it all up for sure because 99.9% of the time thats the end result. Not question about it.
Best of luck dude. But please listen to experience and not your heart right now. If that fucker starts acting up like Im sire it is, read Kill Beatrice over and over man. It helps.
