Caught my teacher being nervous while talking to me...

I’ve liked my teacher for over a year now… I had her for a little longer than a year now and I started to catch feelings for her almost imminently... I've tried REALLY hard to forget about it and get over myself, but the feeling have only increased and gotten more intense. 

I have tried to flirt with her a couple of times and that have resulted in VERY mixed signals from her... I catch her looking at me OFTEN and when I had a singing lesson with her earlier this week, I caught her stutter when I looked in her eyes. I looked up and met her eyes and we stood there looking each other DEEP in the eyes and she STUTTERED then looked away, breaking out eye contact, which is REALLY weird because she is never the one that breaks eye contact... Did I catch her red handed getting nervous when we had, kind of, a moment... 

We have each other's phone numbers and we chat sometimes over private phone numbers. She can send red hearts and she compliments me a lot, not only over text, but in person too!

I don't know why I am writing this here... I think that I just need to get this out of my system...
