how much child and spouses suppose would i recieve . and does he have to pay half the bills

Determining the amount of child support and spousal support requires the review of a number of different factors.  In child support, it is necessary to look at the number of children, he number of nights the children spend at each parent's house, the amount of income earned, etc.  For spousal support there are also various requirements including the length of the marriage, the age of the children, the work history of the parties.  There is usually not a rule of paying "half" because you do need to take into account the income of each party.
