Too young

I was friends with this boy in the 4th grade and his mother invited me over their house. Unwittingly, I went because I was new to the school. But his mother was pushy and before I knew it, I was her son's girlfriend. In retrospect, he was a nice kid. I was kind of mute and played a lot of board games in their basement. I don't even think we held hands, but his mother made us romantic, candlelit dinners whenever I went over. This went on from 4th grade til 6th grade. I guess I was so quiet that I just went along with things. Today he won't be my friend on Facebook. I want to ask him if he blames me or her.
