What should i inbox him???????????????????????????…

I'm in seventh grade and i'm a girl. I like this boy named andrew who i went out with almost a year ago. He hasnt had a gf since and i havent had a bf since then. I still love him more than i did when we were dating. He told my friend a few weeks ago that he might ask me out again this year but he never responds to my texts and he never responds when i chat him, and this is only like once a week that i even try texting or chatting him. I really like him and i cant talk to him in school because i dont have any cles with him. I want to inbox him on facebook but im no sure wut to say. I want it to eithr be along the lines of asking him if he is ignoring me or just saying i miss being able to talk to him and we should talk more. what should i say???????????/
