She told me if she had any doubts about being a jw, she would'nt do it.
Mackey, if she doesn't have any doubts about being a JW, why is she persuing a relationship with you? I'm a little confused...don't push her too hard my friend, it will eventually work against a relationship, give her space, and allow her to decide for herself, this is a MUCH bigger decision for her to make than you may ever fully understand, not having been a witness yourself.
After she reads COC maybe she will have a better idea what the Org, has done, the coverups etc. Print out other material found on the web, like Gerard suggested, BUT don't PUSH, the harder you push the harder she may resist, and you don't want a relationship beginning with regrets. The other thing is, maybe she has the idea in her head that she can convert you?
Hypothetical: What if she does leave the org, then after you marry, and after she gets dissed, she decides she wants to return, then what will you do?
Think about the scenarios, ask her, be honest with each other, that's the only way a relationship between couples can work. And don't forget when she makes your relationship known to her parents, (presuming they don't already know) they will give her much grief. Anyway hope things work out for you.and her.
Good luck
