I feel I should put my 2 cents in since my situation was very similar to yours. When I met my now husband he was a mostly inactive jw. He didn't tell me for many months that he was raised a jw and when he finally did he downplayed the importance of the religion and made it sound like it was just how he was raised. I didn't think anything of it and had no idea that it was really a cult disguised as a religion. We married and lived without anything jw in our lives for many years. We lived a normal life with Christmas etc... So fast forward a couple decades and when his parents died things changed. His family started working on him and pulled him back in. Then they started working on me and I started going to more meetings, conventions, studying etc.. Once I learned what it was really about I wanted nothing to do with the jws. Now he is semi active and basically lives a double life. Things have dramatically changed between the two of us as well. I am now seen as worldly and have been told that I'm a follower of satan. I know this sounds shocking, but it's the norm for a jw. You either follow jehovah or you follow satan. He regrets not marrying someone in the truth and uses me as an excuse to his family as to why he hasn't progressed more in the religion. Those types of comments never came out of his mouth until he became involved with the jws again. He struggles with all of the guilt and pressure to hurry up and get on board before it's too late. As always, armageddon could be here any minute and if he doesn't survive it he will never see his parents again. His family tells him this weekly by either phone or text. It's not a happy way to live!
I apologize for the long post. Please think very carefully before you pursue any type of commitment with your boyfriend. I know it's probably not what you want to hear but this jw indoctrination can be seriously damaging even if it is dormant for many years. I wish forums like this would have been available back when I was deciding to get married. I had no idea what marrying a jw would mean in my future. You are much more informed than I was and that is a great thing. I wish you the very best!
