Going back to the original poster, I would tell your friend NEVER to get involved with a JW, or someone who is intent on becoming a JW. JWs should only ever marry fellow JWs - mixed marriages DO NOT WORK. You may hear about some couples who can stay together with one in and one out, but it still puts tremendous strain on the marriage. Think about it. For the non-JW, they can't really have their 'worldly' friends over and they aren't really welcome at the homes of their JW partner's friends - that's assuming they even get an invite. I don't. My husband gets invited to JW get-togethers but, even though I am not disfellowshipped or disassociated, I rarely get an invite - how rude is that?
Then there are 'worldly' celebrations - I may get to the stage where I want to put a Xmas tree up, celebrate my birthday, go to a friend's birthday party - but I can't.
And if children come on the scene, you are well and truly up the creek!
It's sooooooo difficult being married to a devoted JW - and even if you really love them, you can't share important things. Being a JW is so demanding - it takes up all his time so my husband has very little time left for me- I come second after the organisation and I hate it.
