What is love you thee?

"Thee" means you, so this sentence doesn't make sense. This is Old English. There is also a band named "Love you Thee" and also a stage play by this name, so I'm not sure what one you are talking about.

Answer

The first response is correct. In modern english, it doesn't make much sense. If you use older grammar forms though, it would mean "love yourself."

Actually it doesn't make sense in any form of English. It is not Old English -- "Loved" in Old English is "lufode" as found in line 1982 of Beowulf and I can't even write how they would spell "thee". It is not correct in Early Modern English either and does not mean "love yourself"; this would be "love thee thyself".
