Tell her in all seriousness that you don't take those comments well, that they're not funny and that if she keeps making them you can't keep being friends with her.
Then if she keeps treating you badly just do what you said and distance yourself. No need to be rude or anything, just be cold and strictly professional in your relation with her, and if she says anything you can tell her that you tried but you don't connect much anymore and that's it. She'll eventually give up and stop trying to be your friend. Unless she's one of those people that can't have anyone reject them and freaks out and hates you, in which case good luck.
No troll is too much for me to handle. I rehabilitate trolls, I train people. I am the Troll Whisperer.
