x2, what Learn2Live said on divorce. There is NO concept of "fairness" that will ever satisfy both parties. Divorce. Divide. Split. Separate. You will be severing a whole that at least one of you is likely still really want to remain in one piece. The "unfairness" starts there and can snowball into every nook and cranny of the effort, even with the best of intentions at the outset. Expectations will beget you a lifetime of resentment. I know. I have a mountain of it from my first marriage and divorce.
Remember, the only reactions and attitudes you have any control of in this situation are yours and yours alone. Not your spouse's. Not your families'. Not the kids.
I would not do this alone. I did it that way in mine. Oh, sure, I asked other people to pitch in along the way...lawyers, parents, friends, new spouse, etc...but I wanted to direct the thing and orchestrate a "reasonable" ending. It never happened and the harder I tried, the worse I felt and the more guilty I became.
