Helen, I don't know what has happened in the past 4 months, although I do see this is a very aged topic.
I just joined this forum, however.
If you feel concerned about your estranged husband, I would have suggested going to visit him one day.
Or, if you are concerned for your safety, ask him to join you at a Starbucks for a cup of coffee, so you can check in on him.
If he's struggling, psychologically, ask him to please get some counseling.
Wow, 27 years. May I be so bold as to ask why it's ended after so long? Did you grow apart? Meet someone perhaps?
And why not get a divorce if you've been separated for 2 years?
Sorry, just curious.
You see, I have a similar situation, married 20 years. And we've been very rocky these last 3 or 4 years too.
So I like to gather information from others in similar situations.
Good luck to you, Helen. And I hope that dream doesn't come true; that's disturbing.
