i can understand what you've all written above and i do not have the advantage of knowing her as well as you. i can only give you my thoughts. i have really been trying to understand our beautiful and delicate female friends and how they relate to us as men.
i have noticed time and again how the need for attention is so strong, somthing we men just don't get, not to the same degree. often times i have seen women crazymaking to gain attention, when we men respond we are often times TOLD they don't want attention, yada yada. even pushed away or they run away. is THIS when no really means yes? i really think so. she may not want this, only you know.
our obvious response, to not do what we were just TOLD not to do. this works well with logical minds. i'm not saying women don't have logical minds. i'm saying this mindset is not logical. role reversal is frequent and this also applies to many WAH.
she definitely has anger. no question about it. as i look at posts above that admit to anger venting, even if it is due to some past reason (often trying to get daddys attention) they are all cries for attention. why do you get angry? YOU feel YOU are wronged and YOU want whatever.
only you know her best. look deep within her. what does she really want and need? what has she always wanted and needed? these likely won't ever change. respond to those needs. i wouldn't ever walk away from her when she is like that. imho, unless you feel like you are going to explode and you need to do it for you. i understand the not feed the fire concept, does she get angrier after you do that or less? short term? long term?
you've been doing this for a really long time and have tried many things. not trying to sound preachy at all. try looking from it from a beginners mind, basic levels on up instead of surface on down. only you know her.
