Have any of yall ever unblocked anyone? (friend/past flame/ex) if so, why?

The only people I’ve ever blocked are people I’ve met on the internet who might show up on my Facebook suggestions lol. And the only one from real life I’ve blocked is this crazy girl who’s younger than me that would claim crazy stuff like people stealing my photos from Facebook or something. I unblocked her like a decade later cause I heard she got married so I assume she’s a tad more mentally stable now.
