The Break-Up

When is it an appropriate time to tell the person "I don't want to be with you anymore."?
How should you do this?
How do you do this well? I want 2 maintain a good relationship.

I guess it depends on the reasons why you do it too right?

Fairness. Fairness is the motivation around this break-up for me.
Being with someone in such a transitionary stage in life is unfair for the other person.
I'm leaving for Canberra next year; and in some ways I don't want to maintain the heartache from being away from a person I love and I'm guessing it would be the other way around too.
I can give everything except for a guarantee.
I've been very temper mental with Mr. F; unreasonable - basically everything you see the girl trying to do in "how to lose a guy in 10 days".
We are two very different people - Mr. F and I. And I think it's better for him to find someone more "suited".
Do I love him? Yes, but loves not enough for me. I don't regret my time with him, because it's been wonderful, even though I've been a total cow.
As I said before, maybe down the track, if it was meant to be then it'll be mine. I've been a total idiot, immature/childish, freakish even and he may not want me again. I'm actually really embarrassed from my behaviour as well. I have this little ounce of hope that when I get back from Canberra (that's if I do which I'm hoping I will) we both might still be single.
Nietzsche wrote something like:
"No one ever says, I don't want to be with you because I'm not good enough for you."
He's wrong, in some ways I think maybe I'm not good enough for him. Because I'm not willing to give enough for F; I've set up too many boundaries.
Time - I don't have sufficient time to offer this person good "quality time".
I don't treat him the way I'd like to be treated or the way he wants to be treated.
Our differences, he and I won't be able to accommodate for each other's life styles well. Maybe adjusting habits and behaviour to reach a median takes time in relationships. Maybe stubbornness(from both sides) + differences make things more difficult.
My mum was going to make me break up with this person; and for a second there I was going to cry because I didn't want to lose the opportunity. But she quickly changed her mind. Funny that – now I want the break-up.

I want to call him and tell him straight away but I'm not sure if I'm mentally prepared for this.
So I'm meant to see him this coming Friday. I'm going to try not to contact him until I see him on Friday. The guilt inside is bad. I make food and think I should give him some because I'm feeling so guilty, but that's actually more like saying I like you (gave him banana cake and sticky rice this weekend).
Do I tell him straight away? Do I let the night unravel and tell him at the end?
Tell him straight away.
Wish me good-luck!

Just as a side note:
I went onto facebook today and my relationship status has disappeared. He is listed as single on facebook now. Funny that.

In my alternate world:
I'd offer him to come with me to Canberra.
He can't afford many things at the moment because he's still studying. I want to look after him until her finishes his studies. That includes his living and other stuff - so that he has a free mind to write his thesis. And it would only be for 6 months not forever, that's how long it's going to take him to finish it. Its a great investment because he has a lot of potential. Then after that we can share stuff. Its the 21st century, its just whoever can afford what at the time. And then we can live happily ever after trying to solve our differences with many many *wuv wuvs* and fights.
But that's a fantasy world. And you can't predict the future.
I actually don't mind if he just leaves me afterwards either. Because then I've given something that I think is romantic - everything. And its sad not to get it in return but giving unconditionally feels good itself.
