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.
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".
