Hmmm, i dont know how you can fall in love just by chatting online. But then again, it all depends on what you interpret as love. I think there is obviously a mental issue there. you are lonely and have reached out to this person as they seem to understand you. They might seem ok online, but when you actually meet them face to face, they could be totally different. I think what you are feeling is 'wanted', and you like it. The fact that they are showing you all this attention which you dont get off anyone else. You will never know love until you have slept with them. After all, after one night you might not hear from them again...
