Thank you guys. The point is, I already know these kinds of replies... That's really what I would have done if I didn't know about the existence of NLP/Hypnosis/EFT/Law of Attraction/Tai Chi/everything else/...
They just don't sound very... NLP-ish/technical, from the explanations to the solutions

Don't know whether you understand what I mean.
Anyway, she did list a few things that she
said she doesn't like about me...
- the fact that I always apologyze/"say sorry" for everything, even the silliest mistakes
- the fact that I sometimes skip answering some of her questions (I usually did this hoping it makes things more mysterious and thus intrigueing, but apparently it annoyed her...), saying "Oh, one day you'll know.", "Perhaps I'll tell you...".
Note: this is something I really did thinking it was a technique to increase the effect of surprising her. One problem though is that I sometimes waited too long to surprise her...
- the fact that I often wait until she decides (on that specific day, I let her decide everything, even the meal we ate, which restaurant to go to, etc.) or say "You decide.", "Anything is OK for me", etc.
- the fact that once we went on a trip and I was totally uncoordinated, disorganized on that day; she probably generalized this...
My own analysis is that perhaps I was not authoritarian enough, and perhaps she read into each of my action that I am a "people-pleaser" and try to hide it with excuses.
If that is the impression she has about me in her mind (and she seems to believe really really stongly in it), what can I do to change it...?
The traditional answer will probably be: by not being a people-pleaser and learning how to be less insecure and more confident, authoritarian, etc.
But success might not be guaranteed... Is there really no NLP-shortcut, as in for speed seduction and all those other things everyone seems to use so successfully?
