I agree, once you start down the legal road it tends to be a rollercoaster and you can't get off. If you can agree things it would be much better, however your home may not have to be sold, you may well be entitled to more than half and do not forget any pensions should be split too. I would advise you not to do anything hasty and certainly do not move out. You do not say what the unreasonable behaviour is but this will have no bearing on who gets what. All your assets and debts are one big pot and can be shared either by agreement or in the end by the courts.
