Ok brokenheartedidiot. I'll do what no one else has done and give you the benefit of the doubt (at least just for arguments shake). I'll take your word for it that you really care for your g/f on more than a physical level, that your "moral lapses"(by JW standards) were due purely to "heat of the moment" situations (kinda hard to believe), or like your g/f, you simply wanted to share intimate experiences with the one you love, and in your case it got the better of your JW judgement.
Basically, on this thread you've said:
1) that you love your g/f
2)that you believe the JW religion is "the truth"
3)if you choosing your g/f over the Org., you'd basically be signing your death warant.
If you hold all these things to be true, then in my opinion, the logical thing to do would be for you and your g/f to be seperate from each other. If you were to be in a relationship with a person you percieve to be your mortal downfall, no matter how much you profess to love her, there will be problems in your relationship. Taking your comments about the JW religion at face value, you obviously hold the Org. in extremely high esteem, high enough to have a delusional apologetic attitude about them (not neccessarily because you still think they're "the truth", since ultimately this kind of decision is a personal one and reached for various reasons. But your comment on them "being humble" about their changes either shows that you ignore the facts you have read, or are relatively ignorant of the facts). If you have such a high esteem for the Society, you'll always think about what you lost by leaving them (in this case a great deal), you'll probably be riddled with guilt for leaving a religion you obviously hold dear, and your g/f will pick up on that. If you really love her, you would not put her through that, and you would simply continue to be a JW. Of course, I find it suspicious that a JW with the level of commitment you have (someone who has supposedly seen the errors, but continues to see them as "the truth"), would even entertain the idea of displeasing Jehovah (in your mind, at least), and give up eternal life for a person who your religion says you should not have been dating to begin with, but as I said I'll give you the benefit of the doubt for arguments sake.
I'll once again implore you to look objectively at your religion. I'll remind you that leaving the JW Org. is not the same as abandoning God. And what's the relevance of knowing the religion of the posters? Even if we were all avid Satanist, that wouldn't make our objections to the JW religion any less valid. As far as pointing out a religion that is "better than the JW's", that is a highly subjective question. It really depends on your needs; what you want, hell some people don't join another religion at all (though they could retain faith in God). You don't even have to believe all the dogma of a religion, if it is a religion that allows free thought among followers. Some of us would probably continue to be JW's if we had the freedom of thought (I wouldn't, though), but that's not possible there. Your whole conception of "true religion" might need an overhall, as you seem to believe the main characteristic in a relationship with God is a religion's dogma, and not its attitude toward helping a person develop a relationship with God (the bible seems to stress the latter). JW dogma is only the interpretation of the GB, you can believe what you want about the bible as long as you're intellectually honest, and approaching it truthfully from the heart. The GB's interpretation is no better than yours.
