Well, so we had a week-long school trip on which we bonded a bit about being "really mature early 20s" who did not partake in the teen-drama that was this class' lifeblood. We went drinking one night, but she was in a relationship at the time, so we simply remained friends for the rest of the school year. After that, we lost sight of each other, until one day, two years later, I found a list of the class' mobile numbers and e-mail adresses, that was passed around at the beginning of the school year. I decided to write her and see how she was doing.

Turned out, she was unhappily married to an alcoholic, lost their child at birth and was filing for divorce. I helped her through a rough phase, in which she was mourning, getting divorced and moving out and after that calmed down a bit, another two years later, we found were actually more than friends. Been together for 12 years, married for 7, kids are 6 and 4 years old.
