Oh, sweet love... I remember it well... from many decades ago.
Let me say first, I believe in love and I am happy you both found it together. That's the easy part. The hard part is that she most likely will be shunned by old friends and family members, that is, unless you get inoculated with the JW germ as well. You will be love bombed. They will try to make you a JW drone too. What a feather in someone's cap, if they can get you studied with and baptized!
If you marry and have children, will you allow your child, if they have a bleeding disorder that the doctors say can be fixed with blood transfusions, to have one?
If you marry and have a hard time conceiving, will you go for IVF? JW's do not believe in it.
Do you like oral sex? JW's don't do it. Watch Tower bedroom rules.
If you marry and have children, will you want your wife and children to be away, not doing fun hobbies, but learning how to indoctrinate others into the JW cult?
If you marry, your JW wife is encouraged to speak out about her faith at every opportunity. How would that work for you if you are invited over to the boss's house for dinner?
If you really love her and marry and do not go to meetings or assemblys with her, she will be treated like she does not exist and that is even if she is a JW in good standing, as in not DF. If she marries you, she will be considered bad association, which means generally, given the cold shoulder at the KHall or people more or less just say hi and bye to her. If you marry and do go to meetings and assemblys with her, brothers will think they have a chance of a Bible study with you, ugh.
I think a great idea would be if you and her asked an Elder and wife to come visit, (or you go to their house) that you had some questions. (Heads up. JW's once baptized are not allowed to question anything! Or you will be disfellowshipped). Say you saw the Australian Royal Commission and that in 50 years, over 1000 known pedophiles were not reported to the Police. JW's are the same if not worse than the Catholics! How do you explain this?
Sorry for the long post.
Truly, all the best to you and her.
