Hi there, Dubstep, and welcome to the forum.  I want to say that its touching and obvious how much you love and care for your wife, the "woman of your dreams."  She obviously must be all that and more for what you have endured for her.  That you want the best for her, without upsetting her, but encouraging her to open her eyes and listen to her gut and heart is obvious.  Evidently, she must have doubts of some kind.  What I mean by that is that if she were full-tilt JW she wouldn't have ever considered being with you or marrying you without either trying to indoctrniate you or giving you the grand ultimatum of marrying her or else never having anything to do with her, ever.  What I have found, from personal experience, is that JW's are very, very conditional in relationships and love.  Granted, not all are, but most are.  It's a removal of free will and being indoctrinated (aka 'brainwashed').  Your story reminds me of something that happened in my life. I met my best friend in 8th grade, and he fell in love with me when we were only 13 years old.  But, I was a good JW kid.  I had bigger, grander plans, too.  I knew in my my gut and heart I liked him, but 1) he wasn't a JW 2) We were too young to date and 3) I wanted to get my eduacation and travel the world.  Ironically, my whole life, I'd been searching for someone like him, with his qualities.  But, I wouldn't--and refused--to listen to my gut and heart.  Instead, I went along with the brainwashing and dated someone 'spiritual minded' and who had the grand seal of approval from the elders in the KH.  I read all the JW books cover to cover and prayed to Jah to help me know that I was making the right choice..and I married him.  Well, fast forward to several years later and I'm sick constantly, and can't figure out what's wrong with me.  Long story short, I leave my husband, reunite with my best friend from 13 years old, and finally understand what "true love" and following your heart and gut is all about!  My now-boyfriend is not a JW, but he pushes and encourages me to think FOR MYSELF and to examine what I'm taught, but has made it clear to me that he will not join any organized religion and in fact, does not believe in God---but he has been with me through my anguish of questioning my beliefs, seeing how my former "friends" have un-friended me, and seeing me struggle, scrape and fight to find the REAL me, and to find what it is I believe.  However, he has repeatedly said to me, "if you think you should go back to the meetings, and if that's what you want to do, then I will support you."  He is simply wonderful when it comes to supporting me and listening to me.
In these situations, there is no real 'answer'.  The only thing I can suggest to is be you, the person she fell in love with.  She loves YOU.  After all, she went against her faith and  married someone outside of her faith.  The best you can do is support her on her journey, but, I do think it is a great idea to ask to her explain some of the whacky JW-isms to her.  With her trying to explain things, she might see the senselessness and just confuse herself.  So, the doubts don't come from you, they come from within herself.  This is what I had to do to get past many of my ingrained JW-isms.  Yes, I agree that you should be prepared for any arguments, and sometimes you have to agree to disagree on matters--like in any relationship/marriage.  I still believe in some sort of 'higher power', whereas my boyfriend does not.  I just make it my policy to agree to disagree on matters, keep the peace, and love the man I'm with because I love him from my heart and soul, not because I'm trying to admire his spiritual qualities or find something to attracte me to him.  What can you say; when you've got chemistry, you've got chemistry.  I often ask my boyfriend WHY he loves me, and to this day he still replies, "I've loved you since I was 13 and I will always love you."  It melts my heart.  It sounds, too, like you and your wife have good communication, and that's just icing on the cake. 
So, good luck!  We are here for you and wish you best on your efforts.  No matter what, you have found the woman of your dreams, and it sounds like you are an incredibly patient and kind man for doing all you have done. 
Oh and by the way, your English is impeccable.  You should teach English as a second language!
