There's a lot about your wife in your post and changes she made during the time she came back. What about you, what did you do in that time period? In your time here before did you practice any DB techniques, if so, which ones do you feel worked for the benefit of yourself and the marriage?
Did your wife ever say why she left in the first time, what made her come back and what is making her not want to be married again now?
Do you have any changes you'd like to make to be better yourself/for yourself?
