I wish I had started reading DR before DB. She may still be in the house. I have found a lot of the things I did are listed in the book and those actions pushed her away. I wish I could tell her I was wrong and I know how to fix things whether she want to come along or not.
Try not to beat yourself up over past mistakes. Everyone here has made them. All you can do is accept where you are now and go from there.
Please don't ask W to read DB or anything else. It will only push her farther away. Don't chase her. Give her the space she needs right now. There's still hope, but you have to back off for a bit or you risk making things worse.
M: A really long time. Crisis: 5 years. She's still worth it.
Life is never made unbearable by circumstances, but only by lack of meaning and purpose. -Viktor Frankl
