I'll keep it as short as possible.
I approached a girl on the street. Made her laugh, got her number and set up a date. We went out, bought her hot chocolate (she said she loves it), we sat down and talked. When I asked her what's the craziest thing she's done, she said she went to Barcelona to meet up a guy (long distance relationship) who then called her and told her he doesn't like her anymore so he won't be seeing her. And she spent 5 days by herself in Barcelona. Apparently she can't trust guys easily now. I took her for a walk on the beach, she was like a little kid - constantly laughing, splashing me with water, loving my jokes. I began escalading the convo, started getting physical. Leaned in to kiss her but she grabbed my hand and said no. I pulled back and told her let's go for a walk again (to distract her). 15 mins later we stood in the water i tried kissing her again she said not yet. I thought maybe she likes to save it before we go. So before we split up I tried being more cautious and leaned in and she said she wasn't ready yet. (I know, I'm a needy muthaf**a but I wanted to pull). Anyway

two days later i text her:
Me: You alive?
Her: Yeah
Me: How's your amazing Sunday going?
Her: it was fine
Me: Just fine? That's not really good, *name* what do you need to make it excellent?

No reply after that.

It's been two days now.

If you wanted to pull, just pull.

Look at it like this: guy with no options hears a girl say she has trust issues, he is willing to put up with it for her. Guy with options hears the same thing, he gives her a weird look, he doesnt have time to waste on some girls baggage, she senses she fucked up. How did you respond? Get turned off sometimes, let girls see it. Get options so its real. If you did have options would you be playing this "hopefully she responds so we can go out so I can win her trust" game, or would you move on to your next chick? If you dont have options, at least act like it. A girl will more quickly put that shit aside if she sees thats she's fucked up. Accepting anything you hear a chick say just makes you look desperate.

The door currently says "Pull" so what do you think pushing on a door that says pull will accomplish?

The neediness came from your vibe( if there was neediness), not from the direct action. Theres been girls that it took 4-5 kiss attempts all in the same day before the kiss close happened. Sometimes it turns into a game. It only becomes needy when you emotionally "need" the kiss as a way to validate you.

Theres a chance she'll pop back up on her own, but as of right now you gotta leave it and focus on women showing you the attention you feel you deserve.
