She is the one... except she has a boyfriend

I have known this girl for about a year now and we have texed almost every day (not an exaggeration I have normal used 1000 texts within the space of 5 days) and she is perfect, gorgeous, funny, intelligent and lost more but she has a boyfriend. She dose flirt with me and says I am the second best looking guy she knows (the first is some guy from vampire dairies) but I am finding it hard to figure out if she likes me or thinks I am a "friend". Any advice?
