You shamed her Tameria good for you .I wonder how long she will be welcomed at their home.? You may very well have that opportunity to make that offer to her again or maybe she will feel that she could be more comfortable at your home than at her parents in a few weeks time.
I just had a quick browse on your first post about this and apparently she just doesn`t want to be a JW anymore and who could blame her ? So obviously they will be putting pressure on her to get back to meetings etc,and you will start believing again so on and so on.
So don`t be surprised if she does take your kind offer up and if she does try not to be the meat in the sandwich and let her find out abut TTATT with maybe just a few helpful hints along the way from you.
I hope everything works out fine for both you and your niece.
