Should you NEXT her on LBJF? It depends. I have too much experience getting LBJFed and having to make that choice, so I will try to write down the way I look at it:
NEXT if:
• You have any feelings of neediness or inadequacy around her, and being around her is hurting the development of your game or your prospects with other girls
• If you have one-itis for her. If you don't NEXT her, then the situation will get pretty messy for either you, or for you both. Trust me, I have been there several times.
• If she is very hot and creating an uncomfortable amount of sexual tension for you, or is distracting you from any other prospects
• If she doesn't reciprocate in the friendship
• If you weren't interested in her personality
• The rejection was painful, and you remember it each time you see her
Otherwise, I think staying friends with her is fine. Here is the basic idea: if a friendship would be healthy for her, stay friends, otherwise, don't be afraid to NEXT her. Do NOT stay in any interaction with ANYONE that is not healthy to you. More experienced DJs will be able to be with girls as just friends more easily, b/c they don't have as much neediness as AFCs. This is a matter of SELF-AWARENESS: you have to know when the interaction of healthy is not. So, I think that newbies/AFCs should generally NEXT after LBJF, b/c they will neither be able to avoid one-itis, or even recognize it. Why? Some guys will be so attracted to the chick or attached to validation from her that they will try to rationalize a way to be around her even if it isn't healthy to them (another lesson I learned the hard way). Also, more experienced guys can use LJBF-girls to meet other girls or for social proof. However, this strategy is probably beyond a newbie if he has one-itis for her.
