Well, it isn't easy when you are feeling disliked by a fellow worker but if you understand why she is like that, it may help. She tells gossip as a way of bonding, sharing "secrets" even though she shouldn't be sharing other's secrets. So she was trying to befriend you and her way probably works with a lot of the other women so when it didn't work with you and you called her on the gossiping, she no longer knows if you like her so she has a guard up. You aren't wrong in telling her you don't lke gossip, reprimending her on her gossiping probably belittled her in her eyes. No one likes to be belittled any more then listening to gossip. I wouldn't bring up the gossip part again but I would ask her out to coffee or lunch and show her how to carry on conversations that doesn't include gossip about others. If she brings up some gossip, just change the subject instead of pointing out that she is gossiping. Best way to keep someone from talking about others is to start asking them about themselves.
