Ok. Here are few things. 1. I think going to therapy could be a good thing. I agree with your brother, to me that's a little step for her. My W has said that if she were to go to counselor again it would be to get direction on these thoughts and feelings she is having. Your W very well might need the same thing. 2. Having said that. It is of upmost importance that you find a pro-marriage counselor. Best way to do that is to find a Christian counselor. Ask around. Research reviews on Internet. 3. Once you go see this therapist or counselor, make sure that both of you are comfortable with them. If not, find another one.
My W and I have found a counselor who is pro marriage and that we both like. If we end up back that it is about progress not having an amicable divorce she knows that. Hopefully you can find the same thing Chris. Good luck
