Easyfill,
here my advise to you:
1st- very imprtnt- that you stop looking at her like "The One." I used to do this when i really liked a girl, and it almost always screws u up, bc it makes you subconsciously needy and too obtainable, nervous, etc. You should know by now that people like and are attracted to what they Cannot have. Act like you have some interest in her but youre an alpha male who has other prospects. So if it falls through so what. youre the fucking man, her loss. this attitude will show through when you believe it and she will notice, but dont overdo it into the cocky ass hole realm.
2nd- to stay out the friend zone- Initiate lots of kino. Still always having lots of fun, but touchy feely fun is much better. It raises body temp and the level of attraction, while also making you seem confident and socially aware of when its comfortable to touch her and escalate. Research and practice Kino Escalation Steps.-
3rd- in addition to help u stay out of the friend zone, lead the conversations, not control, but lead to keep a sexual frame, if u dont know what that means look at captain jack's blog. Hes great at explaining the significance of keeping the sexual frame.
4th- DHV
5th- continue to subtly push/pull- verbally and physically
6th- get drunk together
. There are plenty of other girls out there who are waiting to be met, so why not meet them? Go out and have fun, don't go into one-itis for your own sake, bro.
