So I hooked up with this girl, and I would love to keep her as a plate, however she lied to me about meeting up with a guy, she claims she just needed his help to diagnose what was wrong with her car, and she told me she lied about meeting up with him. So she came clean and seems like she's getting attached to me. I have no plans in dating her and just want to keep her as a friend with benefits.

How should I go with doing this? I told her I hate liers and have no interest in a relationship right now. Should I drop her or keep dragging her along?
