But something tells me if I do and there is reconciliation, why do I feel I will be the one with the greatest scars from this process?
That is a decision you have to make for yourself.
As far as you having scars, you may be right, or you may experience something like PTSD. I don't think either person goes through this and comes out the other side without some type of emotional affects for a while.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
