I think my college professor has a crush on me, do you think so?

well i am taking western civ. i began to notice that in class he would stare at me alot. he is a very handsome man he has blue eyes jet black hair a major turn on for me everything is ha ha. well anyways i wrote a paper, then when i got it back i had a b- so he gave me a chance to work on it he even took the time to explain in detail what he thought i should change around. After i turned the paper he choose the subject i wrote about and educated the class about it. Later on we talked again, this time when i talked to him we had a conversation that lasted for an hour he said he liked my paper every time he sees me he face lights up and he is constantly smiling at me. Truth is he even sorta admitted it, when my ring tone went off( my ring tone says you been a naughty naughty girl) he then makes a joke about me which usually teachers don't joke around about that stuff one of the students said something but he just replied that i was no longer his student anymore XD. but i don't know what to do.
