Another "7th grade dating" question.?

Well he deffinately likes you and is maybe a little intimidated by your looks idk,but usually younger relationships (im not trying to say your too young, cuz your not) are more in that awkward kind of stage because your new to the whole dating scene and he might not know how to react to you, like how he put down the arm rest...personally i think hes just very nervous, is this a new relationship? if it is just give it time and get to know each other better, joke around, it may loosen up the tension for him
