Opti, stop validating her being free to do whatever she wants... she is a MOTHER and a WIFE, she is NOT free, she has commitments and obligations... YOU need to acnowledge those and eduate her... don't tell her she's free to do whatever she likes... you are just enabling her behaviour
WIFE : I have to move out
YOU : You are a mother and have obligations, if you want to destroy those and act reckless, don't expect me to join you... I am going to be an adult... you are welcome to join me
