I think this has nothing to do with women and everything to do with who breaks up with whom. Assuming that there’s not betrayal involved, a rejected person wants nothing to do with the rejector; the rejector, though, almost always tries to… hang on to that relationship. That’s my opinion, anyway.
I find that social media makes that healing process worse. At least without it you don’t have the reminders feeding into your current sorrows. It’s just so easy to peek into another’s life even if you don’t want to (try not too) etc you can’t help if because curiosity about your former best friend/partner is strong. Easier said then done would be to disconnect for a bit but it’s hard to do for sure.
