Friends and family have the BEST intentions but unfortunately aren't armed with the right ammo. The best way to fight for your marriage is to not fight at all. Every time you open your mouth it reminds her of the negative, it reminds her of the problems, it reminds her that she would have to work and put in effort to make things okay - this is not something she wants to do ....right now.
Okay again, not trying to be mean but you need to re read what you wrote...
Your W is in the park with another man who is NOT her husband and you call her out on it and YOU embarrassed her??? She is embarrassing herself for doing it in the first place.
She knows how you feel without you telling her, be a STRONG man that wouldn't take her crap. Who did she fall in love with? A man that would let her walk all over her or a man that took charge and didn't put up with stuff like that?
If you were first dating and you caught her doing that, you would have probably ran for the hills.
What you did is done, don't back track on it now and try talking with her about it, it will further fuel her into thinking that she is somehow right in her current twisted mindset.
Just leave it be, let it go... there is not one thing you are going to do to make or break what happens. That is something that is both good and bad.
I remember thinking H has done so much damage (last BD) that he would never come back just to save face. He had done such terrible things and the road home was not smooth in fact it was filled with sink holes but you know what he did come back. He put all the stuff he did aside and ate his words. IF someone wants something bad enough THEY WILL DO ANYTHING.
