Thanks a bunch for all of the advice and support, everyone. But let me explain a few things about him, too, that might be more insightful as to his confusion:
He wasn't born in to it. His mom got into it when he was a kid; they were previously Catholic. He was pretty young, so she started taking him and some of the family with her. It wasn't his whole family, and his dad has never gotten into it. But he's never protested her going or any of his kids going. As such, he's been attending for a long time, but he's never been baptized. So really he couldn't get disfellowshiped for hanging out with me, unless he decides to get baptized. And only his mom has been baptized in his family. Most of his extended family doesn't go. They're mostly Catholic. I'm not sure if he ever even will get baptized. I think he's afraid of what may happen if he ends up being disfellowshiped or leaving. He figures that as long as he's still unbaptized, it can't completely ruin his life. And as for dating a "worldly" girl, he hangs out with a lot of people who are "worldly." His three best friends, myself included are not JWs. Of course he's known the others much longer than me, and I know he only really paid attention in church when he became an adult. (We're in our 20s, and neither one of us is really in a hurry to get married right now.) Oh, and he really does follow the "rules" fairly well. Apart from his associations with those of us who don't go. And though we're not perfectly "innocent," we haven't actually had sex. And we've been together for a long time. Although the things that we have done are probably against their rules. I'm a dirty heathen who corrupted him! (Even though, as the typical guy, he initiated the third base stuff... =p)
I have made the point that most Christians are well behaved if he's worried about a church, although his point is that we don't preach. I always say, if we don't preach, how do other people convert? How are there millions of new Christians every year? It doesn't really phase him. And of course I can point out that even non religious people usually have a similiar moral code, apart from sex. The idea that anyone who follows religion is going to be better behaved is fairly stupid anyway. The only reason many behave is simply out of fear or expectation. They want to act out; they just don't.
So I don't know. Since he obviously harbors some doubts (won't get baptized, admits some things are wrong, hasn't completely committed himself to it yet), I feel like it should be easier to get him to see things. He's an otherwise very intelligent person. I just see him getting more and more mixed up in it, and I feel like the fact that I'm so strong in my faith makes him want to be the opposite and show that JWs have stronger faith than the average Christian or something. And it's SO hard when it seems like he's starting to be a bit more objective, and then it falls apart. It's got to be guilt or fear. When you're exposed to this stuff from a young age, it's got to make questioning and considering other things seem incredibly hard. Especially since he sees these people ALL the time. I don't go to church several times a week, just once. And I don't have time to join one of the Bible studies because I work so much. I usually just end up studying on my own, or sometimes we can study it together civily. And that's one of the times I "innocently" use scripture that I know they disagree with to have a talk. I remain calm and see him get that face.
It's just frustrating. I know and have completely come to terms with the fact that we won't end up together if he stays. Don't worry about that. I'm in no danger of joining. I wouldn't want my future children to be hoodwinked by "religion." I'm about more of a personal relationship with God anyway. It's the only way that makes sense to me. Church is important, but it's hardly essential to being a good Christian. And I am honest when I say I'm not completely worried about whoever I end up with not being religious. In some ways, that's better. As long as he's apathetic enough to let me take our kids to church. Although being with a Christian guy would be fine, too. It's just things are so right with us except this stupid thing, and it's so hard for me to see something I view as petty get in the way.
I'm going to ride it out, use some of your tips (which I IMMENSELY appreciate... thanks!), and see what happens. If there's no change of heart, I will end it. And don't worry. I'm not using that as some sort of ultimatum. I know he wouldn't want to end up with me if I wasn't a JW anyway (assuming he stays), so it's kind of an unspoken truth between us.
