starcrossedpimp,
dude, iam in a situation very similar to yours. we've been going out for over 1 1/2 yrs. after about 6 months of going out, I started studying. We are totally in love and dedicated to each other. I cant see myself without her. But Ive painted myself into a corner. The feeling is I cant just tell her I want no part of religion. I would recommend you telling her the way you truly feel. If you dont want any part of religion or their rules tell her. If you will study and maintain a open mind about the material being presented to you and also accept the JWs have the truth, go for it. Iam not critical of either path. This may be the religion for you or maybe not. Its your choice.
Just remember that there are other matters here then just you and her. Its been easy for my to say " I make my own decisions and stand by them". But she still lives at home and has to respect their rules. The one thing that haunts me, and I hope it wont you, is the family/religion dynamic. If she chooses you and leaves religion...then her family kinda cuts off communication, will she grow to resent you later. If you join the religion and later want no part of it, will you resent her for telling you to go in in the first place. Look at the future, kids, meetings, holidays, etc. Take a honest look at yourself in the mirror and where you see yourself in a couple of years. That includes career.
No one on this board or anywhere else can tell you what to do. Just get all the info and make your own decision. Just discuss everything with her career, kids, meetings, field service, holidays, your family and hers, etc. Leave nothing out.
I wish i could do some of these things before things get too painful.
