If it helps I mapped my spending last year into categories, a full breakdown, I am a frugal kind of person though. It's not totally the best guide given we stayed home a lot last year and fuel was super cheap. PM me if you would like a copy. You seem to have your mind set on the move, persistence and hard work can make the difference.
We moved out almost 7 years ago with a small child and two early teens. It's been great to show them a different world. they have done great from the move. We are starting to consider returning home, we have a reasonable life here but it is just not for us long term (the characterless suburbs, lack of choice, refusal to progress/innovate, and there is only so many times you can see a beach) the kicker our two elder kids are young adults and have decided their lives are here. So we are now in a limbo state.
