Female friend problem..went too far.?

First let me say that I'm biual.So last night I had a friend sleep over at my house. She claimed to be straight but I'm hard headed so I had to prove her wrong lol. So I got up and kissed her. She obviously liked it because she let me walk her to my bedroom. We all know what happened there. But before I even tried to undress her I made sure I told her that this was as far as it would go. No relationships or anything. She agreed. This morning I woke up a little bit after she did. Man this girl was sittin up crying. I'm like wtf is wrong with you. Now she claims to be inlove with me and says the only reason she agreed to not get into a relationship was because she wanted the so much. Sounds retarded to me but whatever. What should I do? I don't want a relationship so that's why I told her that before I put my tongue near her. Sorry for the detail on that one lol. But seriously what should I do about this chick.
