According to that translation. Obito said "koibito" which means lover. That must be the Viz version, god forbid anyone suspect the characters in the books they're publishing might be gay so they'll call it girlfriend just to be safe.
I bet Itachi made a last request to Tobi to make sure he one-ups Sasuke in one more area, "Make sure you tell him I had a lover too." Another reason for Itachi to have had very little time to spend with his little brother.
Sasuke and Itachi are always getting the hot chicks, they're from the Uchiha clan after all, no one cares about the other fodder ninja's in the Narutoverse.
Of course he probably had a lover! He was capable of feelings. Doesn't matter if they were male or female, but it is sad that the published manga would censor it if it was true.
Reminds me of when they cut out that hilarious panel with the naked (convenient cloud coverage added) Sasuke and Sai that Konohamaru transformed into for Sakura.
