I'm hesitant to write this as I took your comment as somewhat of a dick thing to say, mostly because the RMA's on this board often provide free general advice, which is a heck of a lot more than they need to do. I know it's certainly helped me a lot.
That said, anyone who has submitted an application can tell you how to write it, but it won't do you any good. My household statement is different than yours, and yours is different from the next poster and theirs is different than the next.
Do you see what I'm getting at? No one can tell you what to write because your household is different than mine and mine is different than everyone else who has applied.
From your posts it doesn't appear that you have provided much in the way of information on you and your partners current situation. All I can see is that you and your partner haven't lived together, apart from two months, not only that but you haven't said that you and your partner even meet the de facto requirement for this visa.
In complete and total honesty, you may need the assistance of a register migration agent. As much as you may not want to hear that, it could help your application.
Good luck.
