I felt compelled to respond to your post. From similar experiences and what I've read on the boards, it isn't uncommon for negativity to actually increase when they are feeling attention, love and the stuff that they felt was missing before, now in the here and present. What sometimes takes some time to realize is their complaints, are they about the past or about the present? They have to look in the mirror for that one.
IMHO hugs might be less threatening and convey more friendship and care first, rather than a kiss. Kissing to me would be the next step on the road to intimacy. Kisses on the forehead are nice, but I've noticed the power of a hug is huge. Even no words, just a hug. Kissing carries a whole different set of implications, like sex and intimacy and those are the next step of questions. I think you did good though, but maybe lay off on the kissing. Remember don't believe anything they say and be their friend first. Women can get sex and kissing from anywhere, sad but true, good friends are rare. This is confusing stuff. Any opinions? Especially from the ladies?
