You've gotten some good advise here SCP, it's a hard road to travel. You should NEVER compromise yourself for someone else. If you are willing to study to show her that you are trying, why isn't she willing to try your side of the fence?? There is no gray area with the JW's it's black or white. She is in fear of losing family & friends, not you. Tough road. I wish you well, keep reading here and it will help you. I'm not a JW but I do have the experience of having loved one. Good luck.
