We, as onlookers, can't know what immediately should be done. We don't know all the details. People often need to live together for a time before separation or divorce for practical reasons. I think perhaps this thread triggered stuff in me from my own life, and I can't really be as objective as I would like, not knowing the parties involved. I have a close friend who is going through a similar situation and I can say nothing, really, because she has to go through her situation herself. I will go out on a limb and advise someone what I think might better serve their mental health, but I can't really paint the whole picture of what that should look like. Hugs!
