Welcome jonza, Unless you and your GF can view and openly discuss Steve Hassan's video Strategic Interactive Approach explained 2003 (1:23:23), run away and find a non-JW, who you love. I know that my advice sucks, but can you imagine your GF believing that she can recruit you into a dangerous cult that will suck out your heart, mind, and soul because she loves the WTBTS more than you.
I was once in love with a "Spiritually Strong" (non-thinking) JW and I believe that she loved me too. As soon as I did not progress with my second Bible Study (indoctrination) with a brother, she stopped associating with me. She was more afraid of being shunned by her JW family and friends than she was of my loving her unconditionally. If we had gotten married, it would have been a ménage à trois relationship amongst her cult persona, her authentic persona, and myself. I know that you love your GF's authentic persona. How do you feel about her cult persona? Do you think that you can ever get her to critically think for herself? Are you willing to risk your emotional health and financial security on your feelings that you could get your GF to financially think for herself?
I'm glad that you joined JWN to learn more. Have you visited www.jwfacts.com and www.freedomofmind.com yet?
Peace be with you and everyone, who you love,
Robert
