I NEED HELP!

6 years ago

I am in need of advice. 
I have a problem with one of my students, he is being extremely disrespectful. I do not mean inappropriate. He keeps on making rude remarks in between our lessons and before our lesson he keeps on asking me to help him with interview questions or grammar and so on, but as soon as the lesson starts he says no he will do that in his own time and for the lesson he just wants to "chat". 
I really frustrates me as a teacher because I put a lot of hours into my activities and lesson plans for each of my student's individual needs. 
I am too scared to adress him because the students have the power to give us reviews and ratings and it can affect our chance to help future students.
I don't know what to do and I would really appreciate some guidance.
