What is his/her problem?

i met this girl a week ago, and she seemed so nice then she played me out. she told me oh your a sweetheart, i love you you should come over, the whole nine yards. then her bf texted me giving me problems saying leave her alone and stuff. i never even texted her she texted me first. now she is causing problems and her bf. i told her not to bother with me and shes psycho she and her bf keep texing me nasty messages. why did she do this to me? why did she lie about everything? i feel so hurt this is why i dont want to deal with women. lol what should i do?
