Why is my exs current "girl" still adding me on Facebook?

[Lacey]

There's no need for you to add her. Send her a message and tell her that you don't see the point of friending each other. She probably just wants to see what you're doing on Facebook to cause some drama.

Your bitterness also shows here because by your timeline of things that happened, she has been seeing this guy for a while, so she is his girlfriend whether or not you want to acknowledge that. If I were you, I would be looking for a new bar for me and my friends to hang out in.

One more thing...if you run into her and her friends and she offers to get your drink in a crowded bar, don't agree to it. You never know what could be put into a drink when it's out of your sight. This is also another good reason find a new hangout in order to stay clear of her and her friends.
