How do you guys deal with needyness?

Like..if I kissed a girl one night then I felt good and powerful and said to myself: "I'm not gonna call her the next day bc I don't want to seem needy" Then..I will text her the day after the next day and we flirt and stuff and then I asked what she was gonna do in the evening, she says that she'll go out but doesn't know where and I text her that I'll join her bc "doesn't know where" is a dangerous place and I have no good use of her when she is injured (I'm pretty sure she got the joke) but no text responce after that. Then I call her in the evening and let it ring a long time, she doesn't answer. I have no fcking idea why is that so but this feeling INSIDE me..the biggest wuss in the world, the king of AFC's is starting to scream and making me very very insecure. Like..I HATE it when somebody has THAT much controll over my emotions and it ruins my mood and self-esteeme for about 3-4 days. I want to be coldhearted and not care about the girl (it's not just about this girls particulary), I want NOT to care if she calls or not..I want to be my OWN source of validation and as steady as a rock.

I'm just sick and tired of this emotional drama, I just want to NOT give a fck if she calls, picks up my call or if I'll never see her again.

It's like..I kiss a girl and say to myself: "ok, you are NOT gonna care about this girl, you will NOT become emotionally attached to this girl." But in the end, I STILL become emotionally attached or something like that.

Can you give me suggestions? And every time if a girl I have k-closed doesn't contact me I feel that there are no other girls in the world anymore that were as cute/beautiful as she. I know that this is BS but my mind just doesn't want to understad it.

If you learn to game when your emotions are involved, you'll be unstoppable. Don't try and prevent them from happening, because by telling yourself that they aren't there, you're creating a place inside of you that's empty because they AREN'T there. Your subconscious wants to fill this gap, so you start to feel these emotions.

The key to not being needy is to have a surplus of women, get multiple numbers when you go out so if you screw one up, you have another, and when you're out of numbers, go out again. There are plenty of girls out there man, the important thing is to not let one make you feel bad about yourself.

And don't say you want to be cold hearted and not care, because your warmth and your caring is what will make the difference, in the long run, between a girl being attracted to you, and being in love with you.

I'd also take a long look at yourself, do you feel like this because you get your sole source of validation from women, and when they stop validating you, you feel empty?
