You and your boyfriend's ex are friends in Facebook?

Personally I don't, if everyone's happy and have moved on, what's the reason? If she haven't moved on yet then more not to add her. Adding ex's to your friend's list will just bring troubles. Anyone can post anything then misunderstood and will just bring unwanted emotions or dramas.

That depends on what kind this person is. If I don't like this person I would simply ignore the friend request. I don't see any point in befriending someone you don't like and you are uncomfortable with. There's no need to pretend and you are not considered a bad person for declining friend requests.
