Oh good to know I was not the only one feeling ancient...
You said you were afraid of him being with someone else, your own sentence would apply:
It struck me the other day, I'm in a new town but it's the same old story...
He would be with someone else but living the same old story. And probably worse, because Life is Tough and does not like it when you do not learn your lesson.
I wish all the best to you, know you are not alone and that by realizing your own behaviors you are taking a very important step !! I am very proud.
