I would just ignore them. After I had a misunderstanding with a classmate (she was clearly seducing me, flirting and all that), I started to distance myself from her and now she doesn't even bother me anymore~ (I found out she was *ed up, manipulating people)
If they're trying to provoke you, the best thing to do is to ignore and/or be indifferent. Works every time, they start getting worried, but will stop after they feel they really lost you.
