sine te non valeo
I'm sure it's not Spanish. Sounds like Italian.
As James says, it is Latin, but not from Latin America, but from the Latium (nowadays Lazio), in Italy (all that old Roman stuff).
sine ("sin", "without"): preposition that requires the ablative case
te ("ti", "you"): personal pronoun, 2nd person singular, case ablative.
non ("no", "no/not"): negative adverb (in English can be found in words like nonsensical).
valeo (estar bien/fuerte, "tener valor", be strong, "have a value"): verb valeo/-ere/-ui/-iturus, 1st person singular, present indicative, second conjugation.
Although I can't seem to find the thread now, you or someone else asked this exact question yesterday, which was given the correct answer: it's Latin and means "Without you I am worthless" (Sin ti, no valgo (nada)).
