I've followed your sitch, and it does seem like there are a lot of simililarities!
You know one small change I've noticed is my W and I call each other by NAME now. When things were very tense between us, we would almost never address each other by name, only when we had to, like getting attention from across the room. Now I notice us using each other's names all the time, in a nice way, like at the start of a sentence. I never appreciated how much affection there is just in using someone's name.
Another small change is the casual physical contact. When we went to the festival last weekend, my W would occasionally touch me, on the back, on the arm, on the shoulder, on the hand, etc. Just little innocent and quick touches, but very affectionate. So far I've been letting her lead. The last close conversation we had about a month ago ended with me initiating several kisses, which were tentatively accepted. Afterwards I felt I was much too forward, so I've completely held back ever since. I'm taking her touches as a signal that she actually liked the kisses, but I'm playing it cool to present a bit of challenge.
