Dude... she does NOT love you! I'm sorry, but one, you don't fall in love with someone because you kissed them twice. And two, you don't block someone you love on social media and tell then you have a boyfriend and don't want to be with them. She doesn't love you, she doesn't want to be with you, and either she has a boyfriend, and therefore is a cheater, or she doesn't have one but she told you she did, and therefore is a liar and doesn't want to be with you anyway. Move on.
