Help: going to divorce

First of all I need to say I still love and very depend on my hu*****and because we are over sea. I am going to divorce him because I see I can not get along with his parents and my hu*****and is more closer to them than me. After a long time thinking I feel I'd better divorce him than stay like this. We have a 2 year old son. I am going to keep our son. My parents are here help us taking care of our son right now. Before I tell him that I am goint to divorce, what should I pay attention to get best for my son and me? We own a house and are both working right now. What can I get after we divorce. To deal with their family, I have to keep an eye for myself because I know my father in law is a very deep thinking man and he maybe plan everyting out already. In CA, is there a seperate time required? I know nothing about divorce law yet, please help. Thanks in advance.
