My divorce was finalized in November 07 after being dragged out for over 2 years.
My ex husband receives a bonus annually (which pays out the following year in Feb).
When I asked him about the bonus he told me via email that he would split it with me like he has done in the past years. Now he tells me he won't give me a dime. We were still officially married for 10 months of 2007. Can I do anything about this? He also told me that he would pay for the utilities on our home for another year or until I found a job and now he refuses to uphold his promises. I have all this on email. Is their anything I can do?? I am a stay at home mom with 2 sons and he is a executive with a large company. We were married for 17 years and I relocated 8 times to advance his career.

Do you have a child support order?
If you don't go get one.
If you do take it back to enforce and possibly re evaluated for an update.

You possibly can take him to regular court rather than child support court since you have the emails
But you are probably better off getting a set support order.

Your divorce was "finalized". What does it say about division of property, alimony, and payment of debts? Did you have a lawyer?
