No one is telling you to stop FIGHTING for your marriage, thats what we are all doing here.
We are telling you to stop FIGHTING with her.
I have this wet bar of soap here and I am going to hand it over to you, to hold for me. Do you think if you squeeze it really hard that you will be able to do that? After all I am telling you to HOLD it.
This works the same way the more you beg, plead, cry, the further away she will run. This is very counterintuitive. Letting GO is the only way you might get her back.
I totally agree with you about the marriage VOWS by the way, and you married for better or worse and right now this is the worse. Loving her enough to let her go and find herself is what you must DO.
