Speed up the process of divorce?

I really need advice seriously. How do i speed up the divorce process that my husband filed? I mean it is making no sense now, he is not interested with his son, he has another lover that he is in love with, but he is also trying not to pay child support, he denied it is his son but he wants 100% custody? I don't think he and his girlfriend especially would want my son in their life. He practically told everyone that he regret marrying me and filed false allegations on the divorce paper work. It is not making sense at all. Advice seriously. I have been having consistent depression and been seeing specialists and doctor told me that what he is doing right now is mentally abusing me. I can't take this anymore. He kept threatening me about taking my son away from me when he also denied that is his son. I am worn out and I can't focus. Partly I still love him and i felt cheated big time and took this marriage seriously and now that we have a small baby that wil turn 1 year old soon. Please advice, he is into this girl and they seems to be so much in love and i know everything that makes me wants to vommit. How do i speed up the process divorce and get child support and move to another states to live? Serious advice please
