Your story sounds very similar to mine, except I was df'd simply for refusing to bow to the will of the WTB&TS based on principle. I did not want to hang around long enough to see if my crazy jw husband would either accomplish his death threats or commit adultery, freeing me to remarry. There are many of us in the same situation. But anyway, why do you have to do anything? Are you planning to marry this man? If so, why not marry him and not let your mom know? Do you know that status of your ex? Maybe he's already committed adultery, freeing you to remarry If you're not ready to marry this guy, then why say anything to your mom? Why say anything to her about him one way or the other?
