I went out with a chick i didn't see for more than 5 years about a month ago and now I was much more prepared in how to handle things thanks to PUA teachings so I did pretty good, had big IOI's.

She was the one that a week later sent me a text message on a saturday night asking me what i was going to do that night, so we got together, went to a house party with some friends and afterwards I had a surprise prepared to her: i had a bottle of wine in my car with two glasses and i took her watch the city lights over the top of the hill.
We both got and were really drunk. From what i can remember, nothing happened and I didn't kino escalate.

After this day, she has already rejected three dates in the past weeks. Apparently she is no longer interested. My question is: What did i do wrong? Not kino escalating? Or perhaps getting drunk in front of her even though she was pretty drunk too?

And my second question is How to proceed from here... I really like this girl and I wouldn't like to just give up on her... I know I need to disappear for a while which i'll do, but what should be my plan in order to try again?

Thank you very much in advance for all your help.

Ummm dude.

"nothing happened and I didn't kino escalate. "

There's what went wrong. Why the hell didn't you escalate? She probably thinks you're a pussy nice guy. It's over, move on.

Give it time. Do you have any place where you know you can eventually stumble upon her and try to regain frame and start a convo?

Yeah... Unfortunately, the more you like someone the more wussy you become... I guess i didn't want to screw anything up and ended up doing just that anyway.
Nope, she doesn't really go to clubs or attend any place in particular in a regular basis...
