lol. You got ways NOW:
1. Met this ASHo&& and threatin him and quite possable fight him
2. Let it slide, forget about it
3. Talk to her, see how she feels about you
From the way I see it, he used you. He told you that she mit say yes but look what happen. This guy or retard is now tell @hit about you and if he gets to her , she mit belive him and she mit never talk to you again. But I can be wrong
