Sorry to hear this Hazel. Many of us have been thru the same thing and no matter who wants to leave first it still hurts.
I made the same decision after 42 years, not that it didn't occur to me sooner, but had everything in place before I moved here so I won't be any help when it comes to lawyers.
You are gonna have to pull up your "big girl pantyhose" and do what ya gotta do. Here's wishing you the best!
