Like I said, those are definitions I have seen before. They are not necessarily right or wrong. You are welcome to make your own category and it won't be any more right or wrong than mine.

I meant for 5 and 6 to both include boys who don't know you exist. Tadzio, the tragic object of desire in Death in Venice is a 5. Whereas just some boy you like but aren't necessarily in love with is a 6. If you are friends with that boy you are in love with, then that's a 4. But those are just my categories, nobody said they are right.
