You have every right to leave the one you are with or get a divorce if you are being abused. Marriage is not a holy sacrament as it is purported to be. You map your own destiny and create your own happiness. You do not acquire happiness through religion. The choices you make would greatly determine what you would become. So press the divorce button if you are being abused and if christianity is making it difficult for you to leave him then divorce Jesus too and move on with your life. I believe you will have the self-fulfilment that you so rightfully deserve.
