The whole 'true wife' along with OP being black and the community's reaction to her getting with the ex screams cult. She was meant to be a Stepford wife that would take care of her husband at any cost. She needs to escape fast
domestic dispute my ass this is bloody stalking and cult-behaviour and the cops better get their damned act together and help her like they are bloody PAID TO DO
Honey, it will be hard, but just move away and if you can, talk to a lawyer about different options but if need be, move first so somewhere far away, don't tell anyone where you're also moving, this guy sounds like a mental case and will keep bothering you. Leave asap.
If someone tells you that you're a waste of time, run the first time you hear it. It will only get worse. All religions are not good or God-like religion.
