Please read Carla's post multiple times - it is the hard truth! I too am a ubm and can confirm that being married to a jw is very difficult at times. For years mine was inactive and we actually did holidays and lead a pretty normal life. Now things have changed and all of the jw 'requirements' are back in our life. No holidays etc... (although I did xmas last year on my own) my spouse didn't participate at all. That part I'm actually ok with. The part I'm not ok with is that even though I haven't changed much over the years, now since the jw mindset has kicked back in, I am now considered a follower of satan. My spouse has no problem telling me this either. I don't attend any church and I'm still considered to be on satans team and not jehovahs. My point is that even if your boyfriend doesn't seem like an uber-jw (and he's not at this point if he is dating you, a 'worldly girl') things can change as the years go on and if he decides to become more involved with his religion your life will most likely become much more difficult because of it.
When I was young and married a jw I knew nothing about them and their beliefs. If I was young again and faced with your choice I would pass and look for someone else that I'm more compatible with. My advice is do a lot more research on the jws before you marry him so at a minimum at least you will know what you're getting yourself into. I wish you the best and welcome you to the forum.
