What are my rights to have divorce redone before the courts knowing my well-being/life were threatened when I filed for divorce from my ex?

My ex didn't want me to divorce him, not out of genuine love for me, but a possessiveness and had offered to pay me far better money if I stayed in the unhealthy, unsafe and dangerous relationship for sex and such. When I refused and stood up for my safety and well-being explaining the valid reasons I was leaving because of the abuse and neglect he threatened me verbally and thru physical violence that if I told the courts the truth about him, the abuse and neglect and he'd not only deny it but would do everything he could to make me pay, threatening me claiming he'd get our mentally ill adult son to stand with him in falsely claiming I abused our son. In fear for my life and knowing the true intent of this man for following thru on threats I spoke to a destitute lawyer to process divorce as fast as possible to get away before I was further harmed or killed. I am trying to be brave and stand up for what should rightfully have been done in the divorce but I don't know my rights.
