Hi,
1- I think she's into you and the LJBF stuff was a "sh1t-test".
You didn't pass but didn't fail.
2- Read "Say no to LJBF..." in the "How To Attract Women" section. Use it.
Then, tell her the reason you can't be friends with HER is, specifically, BECAUSE you like (not love, huh?) her, you can't only be her friend.
The way you are now, I don't think you'll need to expand too much on the subject. Say it, it's done. She knows. Move on to your usual routines.
3 - Enter Phase 3.
Phase 1, meeting/approaching her, Phase 2 Comfort, Phase 3 attraction (Kino Escalation, teasing, making out).
You can use all the behaviors you mentioned for that.Mmaybe not thinking about other prospects though. You don't need to verbalize it so directly. It's a turn-off for women.
4- But yeah, you should definitely use more light sensual kino. Stop (if you do so) the buddy-like kino (hug and stuff)
So, kino escalate.
5- TEASE her. You need to show her you're not that needy, you're not only being nice to her. But always with a smile. (One or two negs won't hurt).
Teasing is always good.
6- You must act Alpha Male when you go in for the KClose.
For example, out of nowhere, stop speaking look in her eyes, at her lips, grab her arm gently and pull her for her to get closer. Lightly touch her chick or take her hair out of the way... And go in for the kiss... BUT stop 2 inches from her mouth and judge her reaction...
If she stops you or turn her head at the last moment, smile and say something like "yeah maybe you're right, we should stay 'friends'."
Go on as if nothing happened but you'll have to try a second time. Same way, more intense when looking in her eyes saying: "Mmmh, those lips... I wanna taste them".
If it doesn't work (again), now you can say "that's exactly why I told you we can't be friends. Too difficult to control myself. Frustrating. Better to stop seeing each other for a while."
And do just that. Stop contacting her. If she doesn't try to chase YOU after that (with I don't know what excuse she can come up with) you'll know she was playing with you and just wanted a 'fan'.
I hope, it won't come to that and you'll make out though.
