Have you ever re-connected with someone who dropped you, or with someone who simply walked away or disappeared, or with someone who you dropped, or walked away from?

I am interested to know about those relationships that went sour. Either they dumped you, or you dumped them, or they just vanished with no trace, or you decided to walk away from them. Did you ever re-connect? If so, did you find them, did they find you, or did you accidentally end up running into them again? If you ultimately met up, how did that go?

This could be a romantic relationship, a platonic relationship, a familial relationship, or anything else, or in between.
