You mentioned that you had issues when your parents split but didn't when you were a child. It seems to be you are repeating the process, no? Is that what you want for your Daughter? Is that to be your legacy to her?
A Marriage breaks down a child is affected no matter how the break down is managed. This process repeats itself all the time not just here.
In terms of legacies,the one intend to leave D8 is that of being the best dad in the world, nothing will detract me from that, whether I live with her full time or not.
For the world cup I follow England but I plan to watch and enjoy as many matches as possible.
