All we can do is hope for the best, enchanted_one, eh? I mean, by teaching them that religion is a personal decision, are you not passing on your own beliefs? I know tons of people who think that religion ISN'T a personal decision at all. Basically, no matter what you do, you pass on your own beliefs to your kids. I think that since I believe wholeheatedly in my own beliefs, I will be able to communicate the essential truth of it to my kids. Obviously, I will encourage them to search for the truth on their own, but I'm pretty sure that they'll be able to find it in the same place I did. It's just a question of which ideas will make your kids the happiest, right?
But no, I don't think I could change my religion for love. I ran into a teenaged version of this question and picked G-d. Now, in the future, who can say? But I don't see my love for another person, or for myself, overshadowing my love for, or current understanding of, G-d.
The same applies the other way. I can't help but think that if someone's converting to my religion "for me", it's really unlikely to be a sincere (and therefore valid) conversion. Now, if I happened to fall in love with someone who didn't share my beliefs, but after meeting me and studying them honestly and sincerely began to believe in them, too, that would be OK. But it's got to be genuine and I wouldn't--COULDN'T--force it.
Peace,
