I Need to Overcome a Bad Friendship

This happened after the party, when she was talking to me just this morning, and what she said was rather hurtful. I sometimes feel a little insecure about myself, and I'm just getting over that stuff, and I wore this outfit to her party, of course my partner loved it and his brother even called me elegant, so it wasn't such a bad pick.
She said that the outfit I wore was rather plain, but the choker was great.... She didn't even hesitate, like she couldn't decipher that what she was saying was very hurtful and not even needed... I don't know, I've got one more event that I'm going with her, and then afterwards, I think I'll just stop talking to her, because everything she says about me or others, is always negativity, and it hurts.
