Hey, NTX. I for one am not surprised she was "feeling good" about you two. As I mentioned on the other thread, I know it's hard for you to see how things are moving forward, as you are caught up in the middle of it. But all in all, I think things are moving in the right direction for you two (even if it is very, very slowly).
As for her being angry...look, you apologized and explained why you did what you did (not to hurt her but basically because she didn't know it would upset her), so quit bringing it up. If she keeps bringing it up, tell her you have already apologized and explained it to her and drop the subject. In my opinion, she is going through the ups and downs, highs and lows, pull in and push away of the WAW and was just looking for a reason to get p!ssed off at you. From what you've described in the past, I think it's best to just give her the time and space she needs for a few days, and she will get over it. Have things moved forward legally with the divorce? If not, that is great. Keep taking things day by day. You are on the right track; I hope she decides to jump on board before it's too late.
