The girl I felt was my soulmate dumped me and came back, dumped me and came back, then married me. Woo-hoo!
Then she divorced me, married someone else a year later, had his child, divorced him, married someone else, had his kids...you get the picture.
I love her today as much as the day I first laid eyes on her, and that was 33 years ago. I've seen her a few times in the intervening years, we get along fine now, the last time she even suggested we try dating again. I declined. Been there, done that. Got the scars to prove it.
Point being, you're going to be okay. You've got a lot of living and a lot of experiences ahead of you. Life is a rollercoaster. Strap in and hang on tight.
