I wish I had a dollar for every time somebody came here with the exact same story. I wish I could give you hope but it never really turns out well, the JW is usually guilted into going back to the meetings and breaking off the relationship, and the person is heartbroken. She is torn between her desire for a relationship and her belief that she can only survive the coming world annihilation by being a good JW.
This is a cult, they have so seriously brainwashed your friend that she is at present incapable of thinking for herself. She is attracted to you, but at the end of the day her feelings of fear, obligation and guilt will probably win over her attraction for you. If you seriously want to invest time and energy into a lost cause, read Combatting Cult Mind Control by Steve Hassan. What doesn't work: attacking the religion or criticising it in any way. She has been conditioned to see that as an attack by Satan and it will just stir up her fears and cause her to run.
What can work is to work to establish trust, remind them of their interests and goals outside the religion and exposing them to critical thinking skills.
Good Luck
