Breakup? Yes? No? Maybe? :o?

Ahh, So ive been with him for 6 months now and we never talk.... Soo I think its perhaps stupid to even be together, although on Facebook he said "I love her" ... How does he love me ;P he never talks to me orr we never sit together. All my friends agree that there's no reason to be together... Plus I dont see anything in common rlly ;P What to do... && How To do it....!? Thx :)
