yup .. just as its been pointed out .. we have no control over what they do. Does that mean there is no hope? No ... you can start rebuilding yourself, realize that YOU did not set this ball in motion but you are strong enough to not be crushed by it ... does it hurt and sting .. absolutely ... however there is a lesson in all this and there is some amazing growth IF you allow yourself to get out of the bed and start living, take control of YOUR life and what you CAN do.
I have been at the divorce table twice, once in Mar14, again in Mar15 ... first one like you .. deep inside I was crying begging and pleading thought I refused to let her see it ... second time, a year later I accepted it for what it was, even told the lawyer when she asked me ... that I felt W needed to do this to move on, not so much because of me, our family or anything that could not be fixed. Lawyer was actually shocked ... a month later W told me it was not what she wanted and she is still sorting things out ... I am still working on me.
Become the man you were meant to be, not to win your W back, but because you have not reached your potential, do this for you.
