MA has the hightest child support in the world.One child might be 25% of gross income, has to pay till 21 years old if child goes to college, plus college tuition.
Alimony shall be temporary. She does share with you your retirment account.
Google search the MA child support guideline.
You have to live with the child to get the child custody. Your chance is small. Usually the mother get the child custody unless she is unfit.
My advice: Get the child live with you first! Try not to get divorce if you guys reconcile.
If you have to divorce, try settle first. If not, attorney fees is significant for custody battle: $200/hr, easily 5 to 6 dight per case.
Good luck!
