It's a long sad story. More than a decade ago I had an EA with a colleague. We realised a bit too late that our friendship was more than that and stepped right back, both agreeing that if we'd met when we were single we'd have "something" but as we didn't we needed to stay apart.
Have seen each other very occasionally at social things since and kept things very light and friendly. Text exchanges a few times a year, just Happy Birthday or similar.
Anyway, I've been single for a while now (nothing to do with EA) and he's just moved out of the family home, by what appears to be mutual agreement.
He's been in touch.
I'm inclined to say get back to me once the divorce is finalised, but maybe life's short and you have to grab it while you can?
