Soft nexted a fwb for disrespect. Ran into her at a social event we frequent, her ego couldn't handle that I ignored/rejected her and started throwing a tantrum infront of everyone. I was unfazed and went on my night ignoring her.

We frequent the same social event 2-3 times a week. She started gossiping about me with other girls there, making me as a bad man, tries to befriend every girl I talk to so she can ruin my reputation and keep tabs on me, keeps an eye on me through the event. I've basically ignored all attempt and she is hard nexted, but that doesn't seem to stop any of the stupid shit she is doing which is really annoying and ruins chances with other girls.

Any thoughts on how I can remedy this? I like this social event and would like to keep on going to it.
