Sorry to hear this. It's really frustrating when we wake up if our loved ones get more attached to the cult.
They are constantly being bombarded with information about weak ones and having doubts.
The good news is that many genuinely good hearted JWs that have become more serious about WT tend to read all the literature and then develop doubts. They study and research more and more until boom the penny drops and the realise it's all a lie.
Keep being loving and spend lots of spare time doing fun stuff.
