I broke up with my first girlfriend years ago because “there was no spark”. In truth I went on my senior cruise, reconnected with a childhood friend I hadn’t seen in years, developed a massive crush on her, and though I did not intend to pursue anything romantically with her as she was already dating someone else, I realized that I had never been attracted to my gf in the first place. I regret that I broke her heart and wish I would have had this realization to begin with, but that’s youth. I wanted more for my life, and I got it. She did too, and much faster. She ended up meeting her soulmate within a year of us breaking up and they have a beautiful daughter together.
