Hey OP here, it's awesome this got posted! Follow up for some people with questions: This girl came to my school while I was out on sick leave, so being she was in the same class as the BF and I; she got to know him before I came back. He told her he was taken but apparently since I wasn't actually there this didn't phase her. The boyfriend is rather creeped by this girl's psycho tendencies, and has tried to avoid her the entire time I was gone, when I came back we figured she would see us together and drop the crush. This backfired apparently. XD Anyhow my boyfriend and I found her and talked to her later and tried to calmly explain that we were together. She was quiet long enough for us to finish. She mostly seemed really embarrassed and actually apologized! Hopefully she'll stop sending me poisonous looks now. :p But all is (for the most part) well now. Thanks everyone!
