What's the best way to get rid of someone who wants to sleep with you?

I still say she doesn't think you mean what you say, or she wouldn't still be trying. The break room and by yourselves would have been the perfect opportunity to say, "Hey! Knock it off!" The only thing I think you can really do right now is like if you go in the break room again and she's there, if you're not going to say anything to her, then turn right around and go back the other way and avoid her at all costs and at every opportunity and maybe she'll get the hint. Don't look at her, don't smile at her, just completely ignore her and act as if she's invisible. She's a bully and she should be reported. I figured she was a co-worker. You might warn her that unless she stops, you'll report her. Or else have your girlfriend show up after work when she's coming out the door and have her confront her hahaha
