I once was that JW baptized boy, we were in our first college year... VERY intense relationship, lasted 3 years, I'm not with that girl now, she didn't had the "patience" for waiting for me to change, by the end she started to put on "deadlines", because prior to this we broke up for good and told our parents that we were not seeing each other, we couldn't hold ourselves and started dating again in secret... It was a very confusing and stressing time, she wanted me to stand against my parents and religion just to date in public like everyone else, and I don't blame her for wanting that.
Now I'm happily living with my girlfriend, we have been together for 5 years, my ex had an important role in my life and in getting out of the JWs... We have a saying in spanish, "nadie sabe para quien trabaja" (something like: "nobody know who you are really working for"), all the struggle we went through with my ex girlfriend made our relationship something damaged... And at the end I decided to try and date another "worldly" girl... With me mentally out and my JW parents divorced everything went different... But all the experience I had before helped me becoming a little more "normal" human being, as I was "born in" and had to get used to celebrating birthdays and all the stuff...
My story could have ended well with my ex girlfriend but in the end this kind of relationship is time and soul consuming...
From my experience, he will try to fit what he wants with you with his "faith", the time he realizes that can't be done, he will need to choose: leave either you or the religion, and maybe try to avoid to make the choice, it took me couple of years and the divorce of my parents to get the change to break mentally free of the JW
You are dealing with deep deep deep indoctrination, that have taught him that almost everything in this world is utterly evil... I suffered and made suffer A LOT trying to make things work ... Anywhow... I regret nothing...
