I have someone like this in my life. It's been 30 years - and we're still friends. It all started when I was 21 and my dad died suddenly. It destroyed me. I wasn't up for the LDR anymore, started dating a guy in my city and got married. It was a terrible marriage, but when I left him and contacted the other guy, he told me he'd been looking for me for two years and gave up - he'd gotten married the MONTH before. Years later, THEY split, but now I was in a long term relationship and pregnant. Turns out my SO despised being a parent, so we split...and by now, other guy was remarried. I got married a few years ago. Sigh. We joke that we will find ourselves together again in our 80s.
