If I don't want to be friends with her and literally don't want anything else to do with her, I'll delete her from social media, but not block them.
I'll still keep their number, just in case.1

I did become friends with some exes on Facebook when it came out, but afterward, a lot of nastiness and drama, particularly from their new partners or wives got to be a bit much. I removed them from my friends list, but I only blocked the ones who became a bit of a pest toward me, including their new girlfriends or wives. No need for that. If all was good and a removal was all that was needed, then great. But in the end, I know how to leave people alone -- completely. If I felt in some way that I was being hassled or private-messaged and it wasn't honest to their spouse, I'd block. If they just messaged to say hi or something simple, no biggie. But some people do a lot more to make life complicated. I knew there was a reason why they weren't in my life anymore anyway. LOL1
