Police say the unrelenting bullying that may have caused 12-year-old Rebecca Sedwick to kill herself erupted from jealousy over the attention of a boy, John Borgen.
Now, Borgen says he's struggling.
"I think about her almost every day," he said. "I could have stopped it."
Borgen is now dating the 14-year-old who police say was one of the girls who told Rebecca Sedwick she should "drink bleach and die and should kill herself because she was ugly."
Sedwick killed herself last month.
The 14-year-old is now in jail.
She and a 12-year-old were charged with felony aggravated stalking.
The 12-year-old is under house arrest.
Now, Borgen says he's on a mission to expose bullies.
There is now an online petition for a new law giving schools more power to stop cyber bullying. It's called Rebecca's Law.
