Me: If I were you, I MIGHT unfriend the ex. I’m guessing she’s just trying to be friendly and heal whatever wounds were there, but she’s going about it the wrong way. It might hurt her feelings but you need to figure out which is more important to you: your comfort or her comfort. You can always give it another couple of months and see if she settles down. The newness of the “friendship” might be hyping her up. But if the behavior persists, you can always unfriend and/or block her.
