loving her is too soon ^^^ but if you really want to know if she has interest in you just come clean & expose your feelings to her. its better to speak than to keep quiet because then your still gonna have that anxious feeling to know whether she does or doesnt.
Someone said that the greatest enemy to success and life in general is fear. As long as you fear what will happen, you will never have a chance of going out with her. Start small like greeting her when you meet and with the passage of time, you will have enough material to make a decent conversation.
