I'm not sure about giving XW the DR book. I remember it's not recommended to give spouse the DB book.
I haven't read the DR book. Do you think it would help me with my sit? I'm still working on letting go and most recently figured out I have a fear of letting myself feel happy about OR. Sometimes when I've got those lovin' feelings I still hold back and up go those protective walls.
Anyway, things are going better than ever for you with XW, so don't push her into OR stuff right now. Do you have the KLA tapes? Maybe you could implement some of those ideas into your DB technique. Remember, when you pursue, XW distances, so don't pursue!
Seems like XW IS working on herself especially in the self-esteem department - she's been exploring new career ideas. Give her space to figure out more about herself and show support by listening to her. It's so great that she's making new plans about her future and she's telling you about it. Another good sign!
