It is never over until it is totally over. Best of luck. The person might still be living with their soon-to-be ex. My opinion is that for most people, by the time their divorce is final, they've been checked out for so long, that the only thing you feel is relief, finality and perhaps a little sadness, which lasts for about a day and a half.
My fear is to support his chaos and grieving process after his divorce and he thinking I am accepting everything and not respecting my needs so loosing attraction for me at the end. He and his wife had left the marriage years before and divorce was really just a formality. This man has been nothing but good to me in so many ways. He respected that. Red flags I should look for?
