Go have fun and if you still think about him go spend time with him.

Do something with your friends to keep him off your mind.
Take your top off.
take off your shirt and let him take off your bra
It'll blow over. Keep in mind: Your boyfriend shouldn't have ignored you in the first place.
Jut your boo-BAYS at him. Seriously.
take your clothes off
ok so well look for a girl your age and go out with her it will take your mind off your teacher crush ive had this problem with my music teacher and i got a boyfriend and he got my mind of my teacher not right away but after a week or two
Do something you like to help you take your mind off of her. Hang out with other friends.
get a hobbie do sports travel spend time with family an friends
I would encourage her to meet new boys/friends to get her mind off things
take your clothes off and use your imagination
