So sorry you are dealing with this. My then-wife did this to me after 15 years of marriage. I begged her not to go. Begged her. To me, a separation was just code for divorce. When she left, that was it. I moved on. It was awful. A year later, she called and wanted to get back together. I think it was financial for her. I know it was. I said no.

You have to decide what you think this means. Go with your gut. That's my best advice.
