Sorry to hear that things have to change this way. The easiest and least painful way to get through this is to avoid getting into the issues that have caused you to split in the first place. If you can both agree to make this situation as easy as you can, and on no account get into rows about who did what to whom, then you can get through this. The only other issue, as mentioned, is the one of money, the last great sticking point. Try and keep calm, and remember, it is sometimes better to walk away with less money and your sanity, than the other way around. Best of luck.
