Its funny I have been trying most of what you suggest! I took a day off, I have come home early. I need to be a bit more creative on doing special things. I have taken to calling her all the time when I am on trips, so she knows whats up. She doesn't want to travel on trips because she doesn't want to go exploring alone while do my business, but that may change.
I have told her to take her time and go to college if she wants to - we have plenty of money to afford that. She is coming around. She says she feels 'worthless'. I don't want to rescue her - I just say I value what she does. She needs to spend some time on forgiving percieved hurts about that - for some reason she feels I devalue har as a person too. I am getting to the bottom of it, but I keep finding surprises.
We have had more intimacy, which has helped a lot. My feelings for her are starting to come around, and I am learning to push her buttons.
