17, 1989, online in a pre-AOL chatroom. Online relationship, lots of phone calls too, was a year before we met. Lasted 3 good years with sporatic visiting.
It worked fine. What does “work” mean? Forever-and-ever-and-always-for-eternity?
Relationships last as long as they last.
It’s not much different from boyfriend’s in the army / long distance truck driver / out to sea, etc. It can work. Better nowadays because internet.
