After over two years of piecing, my W recently brought up the spectre of divorce.
She doesn't want to talk about it either, so all I did was offer to talk to her if and when she ever decides. I offered to honestly answer any questions that she might have about my feelings and intentions.
If she wants to know how I truly feel, she'll ask.
Sometimes you can rebuild together. Sometimes it's all up to you. Right now, it's all up to your W. In times like that, you have to keep your nose out of it.
Sucks, doesn't it, KAW.
Sorry, my friend. All you can do is bide your time until she invites you back into piecing.
Just be the fantastic KAW/husband/father that you are, and wait.
