HOW TO GET THIS GIRL INTERESTED?

Try asking her about school and/or if you can get someone to talk to her for you and find out what she likes talk to her about that and/or she seems to like this mr. armstrong so if he does anything in class worth talking about talk about that then try to get the conversation to other things too to keep it going! i have the same problem but i found out what he likes and it helped out a lot to have something to talk about that he liked. Good Luck!
