I know I only said ditto. But I will put in my 2.21 cents.
With time, for anyone, comes the potential for growth and maturity. With both of you further along in life and possibly more experienced in relationships, that changes the dynamic of the relationship.
Life circumstances change, career, things in the personal life might be more in tune with maintaining a relationship. If you had a good "friendship" and continued on with a good friendship, then there may always be a chance.
There is so much involved in a relationship, I would always be willing to look at a relationship with someone again if there was true love there. It would never be off the table for me. I have always been good at looking to the future instead of the past.. I think thats a big key.
Well thats my optimistic view on it anyways.
