What more can I do? If I am patient and just work on me, then she just continues to put in time until she can execute her escape plan, and I continue to get my hopes crushed. If I push her, she will likely just move farther away emotionally.
This is where detachment comes in. You have to understand that you cannot control, fix, or make someone feel differently or the way you do. You can call them every name in the book, you could point out scripture, you could leave a 100 books on the coffee table, etc, but until they choose to ask themselves why...they won't.
This is where DB shines. You can know and ask for what you want. You can look back on your marriage and eventually KNOW why her emotional needs weren't being met. YOU can KNOW what you did wrong and "silently" fix them.
You are upset right now, but I do get the feeling YOU KNOW where you failed. All you can do is better yourself.
In the end...you know your Wife better than any of us. YOU have to become someone she would be a fool to leave.
