What can I do about being in love with a teacher?

So I started liking my teacher about 1 and a big year ago and I love him. Not like. Love. Everytime I see a brand of the car he drives or the brand of the clothes he would normally wear it just makes me think of him. Anyway I had him for class quite a bit and he lives in America now but is coming back in 2 years. I don't know what to do as I am really in love and obviously I can't tell him, he is also around 10 years over. Please help or just tell me what to do??

meet other people and stop watching pretty little liars
