When I was freshly "out of the religion" but still believed all the teachings I was dating a nice young woman. We were both 23 years old. I still believed but wasn't really going to the meetings and still considered myself a Witness - she loved me enough to actually check out the religion.
She went to a couple meetings (without me knowing) and aranged some meetings with the elders to ask some questions. I recently had contact with her 7 years later. She revealed to me that she looked into the religion. Her reaction, at the time was, "these people are wacked". She even ripped up my blood card, while we were dating, because she wouldn't let me die because of that religions stand on that issue. She was honestly SCARED! She was horrified about a lot of what they believed. She loved me but in no way would ever be a Witness - her words exactly!
Here-in lies you conflict. If you accept that your fiancee will remain a Witness, you respect that but it's not for you...............YOU LOSE! Jehovah's Witness don't accept that. You and him will be looked down on by all his JW friends and family.
Why don't you do the same - set up a meeting with some of the elders and ask questions. I guarantee you won't get any straight answers or you will be confused/persuaded if you don't have any bible knowledge. You will also see that aceptance and love are conditional on you being a Witness. Please be careful! No matter how strong your love is it can not even compare to the gripping controll the Watchtower has over its followers!
