Ciao Czechman
I'm italian and what they said is (or at least it looks) like a great compliment. Correcting what Jaymc said, "superbe" isn't "arrogant" (like maybe in French), but exactly as in english: "Superb, wonderful, outstanding.."
The fact he/she is writing you in slang and what he/she's saying is quite intimate.. and strange. to tell the truth, if it wasn't your girlfriend or someone loving you, I'd say this is (take it with tongs) even a "whore". Especially coloured women coming from Africa use here the word "amore" to attract customers. "Buono amore mio" isn't something you say to the first passing on your road.. I'd deepen the knowledge of that girl (I hope is a girl...) if you are single..
All the best and let me know if you (or anyone) has other question concerning Italian.
