Does she like me?? help!?

[me]

so i met this girl a bit ago and we talked on twitter harmless enough right? then she gave me her number, her idea not mine because twitter was "annoying to check", so we have been texting for about a week now and every day she texts me first , each morning saying goodluck on your test or something or she will text me randomly at mid day then we talk all night long then repeat next day i have no problem with it at all , we have soo much in common its crazy, then i play guitar so she asked me to come over and teach her! so i went over and we talked the whole time like never a really dull moment taught her guitar a bit, showed off whatever, and i just felt like we connected it was crazy then the only thing is , she has a boyfriend.. im so confused please only actual helpful responses because i really like this girl shes gorgeous and so fun to talk to and i really cant get her off my mind please help???
