I guess I don't see how you are judging him as such. You are determining if you are a match. If you can live with him and have children with him....yes I know, not today...but someday.
Why is his stubborness any different from any other trait that might turn you off. We "judge" people everyday based on looks, smile, intelligence, etc. There are some things in life that just ARE NOT meant to be. You might have the right man at the wrong time. Or you could just have the wrong man. Doesn't matter. The end result is the same.
Think of it this way. Right now, could be the best the relationship gets. You seem to think that it will get better. And while it may...it might also get worse. As it is....this could be the best it gets. Is that enough? You mistakenly think that if you make some movement on your own beliefs on Xmas and such he will make some movement as well. This is complete folly. He won't budge if he's a good JW. Won't happen. Not today. Not tomorrow. Not next year. Let me say this one last time....are you listening? HE'S IN A HIGH CONTROL CULT! Get it? If he is a good JW, YOU WILL NEVER COME FIRST. You will ALWAYS come AFTER the religion.
So if you want to live your life where you are not as important as his religion....knock yourself out. If you want more than that. YOU WILL NOT find it with this man.
