Attorney fees to divorce narcissist husband

Hi, my name is anonymous for legal purposes. I am looking for help to pay attorney fees for divorcing my husband. I am finally taking steps to get myself and my two children away from a toxic, manipulative situation. I asked for separation six months ago, hoping we could be civil and cooperative enough to take care of this separation through a mediator. He has strung me along, given me excuse after excuse as to why he wasn't contacting the mediator. All while making no financial contributions to household expenses, i.e., mortgage, food, utilities..etc. (and refusing to leave the house). He has recently disclosed to me that he has started a new relationship. That, coupled with the newly learned knowledge that he has been unfaithful for most of our relationship, has made me realize I will be forced to do this independently. I have contacted an attorney and begun the process of having him served. However, attorneys are not cheap. Any help is appreciated.
