Scorpio is back, but . . .

I have posted this on the Scorpio Board, but may as well post it here in case any capricorn may be able to help with advice.

Hi everyone,
I badly need insight into this dilemma.
Years ago I had dated a scorpio, and it was NOT about sex, but moe about friendship and companionship.
I knew he was married, with kids, but he was not living together with his wife, because he worked in a different country, and was only seeing them on vacations.
We did have a very special thing going, but I ended it then, abruptly after about 6 months together as a 'couple' and more as colleagues, because he did not take any steps towards ending his relationship with her.
Now, about 16 years of not hearing or seeing him ( I honestly did not care for heartache ) I get a phone-call from him, and I was flabbergasted.
He seems to have been looking for me for years, asking everyone I/we knew about my whereabouts, and I believe him.
He invited me for a 'cup of coffee' and for the sake of old days, I accepted his invitation.
I am divorced, and my kids are both abroad in college, so I have a lot of time on my hands; besided I do feel a bit 'lonely' at times, but I get over it.
He was still being 'vague' about his wife saying that he will talk more when we mee, which I assume he has not divorced, and probably never will, but I know for a fact that he stays for extended periods away from his family, as he works in a different country; besides he mentioned something about her that has not changed.
Any insight into this ( I am over 50 so is he ), and/or advice from 'faithful' scoprios (and/or Capricorns who have been in the same situation) here is much appreciated. Thank you
