Does my husband’s bigamy affect my divorce proceedings?

My divorce from my Muslim husband is pending in court in Charlotte. Despite this, I have learned that my husband married someone else at the mosque and is now living with her. He is not paying me any financial support or paying our household bills but he is now supporting a new wife. What affect does this have on my divorce proceedings? I am not happy with my current lawyer, what do I need to do to replace him with a new lawyer? I want a lawyer who understands Muslim culture and Islamic law to represent me.
