I'm sorry but how can you be raised as a witness, baptized as a witness, and not realize that your mom is going to feel obliged to report any kind of "wrongdoing" to the elders??? That's how JWs think, that's what they're programmed to do. They're a cult.
Dont play their games. Don't admit to anything. If they stop by, be friendly but evasive, don't let them inside. If they call and want to set up a meeting, either politely decline or accept but just forget to actually show up. Any way you could just move again, maybe change your phone number too(without telling your mom, the informant)?
No Apologies
