Tweet

I met a boy 4 month ago,we talked everyday on Internet.THEN suddenly we found that we were classmates in primary school,we had not been touched for ten yeas , it's really a big coincidence,we both surprised .a month later ,he confession to me and i didn't refuse him.we phoned each other everyday but he never date me though we are in a city ,and what's more ,he keep touches with several girls in a dubious way,now i'm doubting that does he really love me,or i'm just a toy that he use it for killing times?can anybody tell me what should i do ?BTW,this is my first love.
