Hell it's not even the same sport.
They aren't on the same page in the relationship. Her view of the r/s is going to be something entirely different than your view.
I share a similar experience as you and I understand how painful it is when you see someone throwing everything away as if it were nothing. It's like talking to a wall because she splits herself and can't accept her portion that would make her feel bad or "black". I understand the frustration blur and I'm sorry this happened to you.
From my experience with my ex in-laws during separation, it's best not to say anything or expect that they will reciprocate. Blood is thicker than water.
Hang in there.
