I completely understand how you feel. It's like, you give them what they asked for...and then still nothing. It gets old. I sometimes think the left behind tire themselves emotionally and mentally before they really detach. I think you are NOW at the detachment place that you thought you were already at. It's funny as the process goes, you realize that when you get to a certain mindset, that you wish you could have done that from the beginning. But I guess it's a process.
I'm not sure why your wife has such anxiety. Even around your daughter. That has always struck me as odd about your situation. She doesn't seem to have a real grip on reality. Not for nothing, her life would be really different if you decide to divorce. I'm not to sure that she really understands that.
