>_< very depressing indeed...yup yup...X_X *sighs*

Aww...I'm so sorry that things had to be miserable for you all that time...because I know exactly what you're going through. I had/have to watch my ex-girlfriend *and* my ex-boyfriend running off, trying to make me jealous by being with other people. It drives me insane...I love your story. It's gorgeous...try to write more on it, if you get the chance.

I like your expressions in this piece. A suggestion for the past and present stuff is to just have the *flash back* sign or just use past tense thing.
Eg. - She had walked over to the bench and picked up an orange.
I've liked these last two chapters. Have you really felt like Jen has? I get the impression you have, anyway, keep your chin up. Life can only get better.

This is a really powerful piece, especially the ending. Try spacing the dialogue better, that way it's easier to read, otherwise really excellent writing.
