I'd invested so much of my own identity in it, I had lied to everyone I loved, cut myself off from my family, lost almost all my friends and been horrifically bullied, so I HAD to believe that it had been worth it, that it really was true love.
But it wasn't. It was a teenage crush and, if he hadn't done everything he could to encourage it, it would have petered out like any other teenage crush. Maybe I would have dated boys my own age and had normal experiences of a first relationship.
Berts, I'm so sorry this happened to you. This is what the apologists don't seem to get. That 'relationships' like this turn the young person's whole world upside down.
When Forrest took this girl away, she became the subject of nationwide scandal. Even though her name wasn't mentioned during the court case, everybody knows who she is. The notoriety is going to follow her around for years. He must have known that that would be the inevitable result of her disappearing overseas with him. If he really cared for her, surely he'd never have made her the subject of public scrutiny in that way.
She's become estranged from her family because of what's happened. Ok, there may have been problems already - very common with teenagers and their parents. But this whole affair (sorry, don't mean it in the love sense) appears to have caused a complete breakdown in her relationship with her family. How can that not be utterly devastating for a young teenager?
And this was her GCSE year. A time in a young person's life when disruption, upheaval, stress, family breakup etc are the very last thing they need to be dealing with on top of intense study and worry about exams 
He is such a selfish bastard to have set a bomb under a young girl's life like this. If he had a shred of decency, he'd insist that she didn't waste another day of her life on him.
