Hi Clay:
Let me ask you a question...if this girl was interested in you, your mom liked her and everyone was happy & joyful, but the only thing she was interested in doing with you was discussing your religion and how wrong it was to her and why you should leave it, would you still be interested??
We all want what we cannot have, and it seems to me you have an interest in her and there is a challenge before you that you feel the need to try. I can attest that having a relationship with someone in the JW's is not an easy task. I can take it a step further & say that even if you get over the hump, you fall in love and get married, you have children. Prepare for the battle to really begin there.
I think you should take things slow, don't try to change her mind on what she knows, but show her other things in life. Show her that you are her friend first, not someone who is trying to take away her religion. She will resist that more than anything, and they are prepared for that as well. If she's saying that you can't go any further, then you have to accept that. You can still show interest, just make sure you get out there & date other people, you are young.
Sometimes the catch isn't worth the chase. Good Luck
