Lol - rule number one about the seduction community: do NOT talk about the seduction community.
Rule number two: if a girl finds out you learned stuff from the seduction community, instead of acting like you did something wrong, turn it around on her. Just tell her that girls are at an advantage because they've been getting help for YEARS on how to manipulate guys into liking them, and that the stuff you're learning is to be used in a positive way.
Think about all the books, magazine articles, tv and radio shows out there for women. Books like "Think Like a Lady, Act Like a Man" or articles like "100 Ways to Get Him to Propose" are nothing more than things teaching women ways to manipulate a man - but again, its in a POSITIVE way. Yet you want to learn how to turn THEM on and now you're being a sleaze ball? PLEAAAASE!
Anyway... as for this girl... what i have found is, as much as they hate to admit it, girls usually respect and/or go out with dudes that they know know the game. So, play it with her. Don't reach out to her, and if she contacts you and asks where you disappeared to, be like "oh, i'm still here - just practicing the whole push and pull thing on you." And laugh when you say it.
If she brings up how manipulative you're being, just be like "hey, its no worse than when you go on a date and put on make up - now, would that be dating the 'real' you, or the manipulative version of you that's using make up to cover up what you REALLY look like. And don't get me started on push up bras and perfume!"
In other words: don't take her seriously. Play with the fact that she knows you have game, then be like "you're just mad 'cause you don't know what kind of game i'd be using on you. Ooh, wait, that's me being mysterious - looks like u found me out!" Then continue going after women. Either one of them will like you, or this one will realize that, despite what she logically feels about you and what she knows, that she wants to be with you after all. But don't feel bad about looking for help, maaaan!
