Basically, she's young, immature, hot, and has plenty of opportunities to make me jealous (ie. she works bottle service at a big nightclub, constantly hit on etc). She seems fond of making me jealous, and enjoys telling me who she thinks is hot and stories about her ex's. I usually just ignore it, retaliate, or lightly tell her to shut up. However, it does piss me off and it's continuing. Anyone deal with this before?

I'm thinking of talking to her seriously about it, and telling her to shut the fuck up about other guys. Is this too severe/chumpy?
