You could title this story "Sometimes it takes years" or "It works on the first try."  Your choice. 

I was on eHarmony for a few years.

Brigid was on eHarmony for a few weeks.

I went on several dates over the course of my membership.

Brigid went on one single eHarmony date.

I was the lucky match. 

I was her first and her last eHarmony date. (She was my last.)
