Anyway, The real issue I take with that statement is the SHE decided what was best for HER, ME, and our children. We did not come to that decision together. SHE decided to leave and SHE decided leaving was better for ME
Totally with you on this. Don't even take her statement seriously. She has to rationalize her decision and explain it to herself and others. She's in a place where it's all about HER. You have to let her ride out this process for herself. That's why DBing will create a situation where she will be second guessing herself.
She did make that decision and you had no control over it. It is a really $hitty feeling and loss of control plus rejection sends the LBS in a downward spiral. That's why DBing is so important for you and getting that control back and becoming empowered.
I know it $ucks knowing someone just made a decision for you and in your eyes gave you no chance to work on things.
