不能对你太好...
If you are going to separate you must come to agreement on these and many more items.
Who gets custody of the kids?
What access will there be? Where? When?
Where do the kids go to school? Church? Summer camp?
Who pays how much support to whom?
How do you share the family assets?
Who pays the family debts?
What do you do about pension rights?
Who gets the credit card bills?
Who gets the house?
Who takes the family pets?
A thousand other things to decide

The separation agreement kit costs $50.
