In fairness to my wife, she is a wonderful woman, I love her very much and she makes my life with the cult quite bearable because she has never been a hard core JW. It seems that your girlfriend is not a hardcore JW. So there's hope for you.
Regarding getting someone "spiritually in" to give a comment, I doubt you will get anyone here. But I can surmise that they will describe a rosy scenario for you... as long as you are in too. And I think that it is possible to be very happy as long as both are mentally and physically in. The problem is that the internet is rapidly drawing people away from cults, so the chances of faithful JW happy couples are shrinking.
