Maybe she would not say rude things to you if you did not call her a WHORE or SLUTTY.
You are not into dating and sex, she is. What she does is none of your business. If you find what she does so terribly wrong then stop hanging out with her and find friends that share your values. If you still want to be friends but don't like hearing about all the things she does with guys, then there is a way to say politely 'I don't agree with the stuff you are doing and I am not comfortable hearing about it' and then changing the topic.
If a so-called friend of mine was calling me naive, easy and a whore, I would drop her like a hot potato. Stop talking to her disrespectfully.
To Trenell, MizKerri and geeky:
I pray none of you ever has to live in a communist state.
Geeky is my hero. She's the true badass. The badass who doesn't even need to be a badass. There aren't enough O's in cool to describe her.
