What ever happened to the first person you had sex with?

Stupid general question. I am in mid 40s and the first girl I had sex with ended up a single mom with a loser dead beat baby daddy.

She did OK as a single mom, she has her life in control and her kids as in their 20s now.

EDIT: I love all the people saying they are happily married for many years to their first. That's kinda nice.
