Since you have been an adult, what is the shortest and longest amount of time that you have dated someone for?

I know most people have those relationships in school that last like 2 weeks, but why did the shortest one you had as an adult end rather quickly?

For the longest one, did you think you were going to marry the person, because of course the longer you stay in a relationship, the more likely you are to start contemplating marriage, and whether or not you can see yourself with that person forever.
