Ladies, this girl acts very weird around me...what is your interpretation?

i think you should talk to her about it, it's not fun to try and guess what someone else is thinking. i think you must really like her because you notice so many little things (like how she wears blush now). maybe you should try asking her to hang out with you, not on a date, but as friends. this will probably clear things up because if it goes well things won't be awkward in school anymore like they seem to be now. even if you just start off as friends again, it could lead to something more like a relationship. good luck! :)
