What should i do next? ?

Okay, i like this guy (BIG SHOCKER!). well, we've known eachother for i'd say about 9-10 years. we went to a football game last thursday and we both had a great time (lots of flirting, BTW). so now i'ts saturday and i don't know what to do now. it was our last football game and now i have to wait for a few more weeks till basketball season. waht should i do in the meantime while our sports are in limbo (i'm not really allowed to "date" and i havent' told my mom about the football game)? should i wait for sports to start back up or what? and what should i do to make sure he knows i'm still interested?
