Help a Reader

I'm posting this as a topic so it doesn't get lost. A reader writes:

I'm looking for a little help. I'm currently with a man whom I love and adore. I recently found out his family are members of this church and am not sure how to handle it. I am told his church is more of the laid back version of it but it still terrifies me a bit. I was raised Lutheran, ELCA. The type of church where you come as you are and listen to his word and you will be saved. Not the strict guidelines I've found online from OALC. Can anyone clue me in on what I'm getting into? How can I talk to him rationally about it? He gets defensive and ignores the topic and it scares me even more. I'm not going to force him to leave his church- but it's not something I'm currently comfortable joining, especially not after reading some of this. Can I ask him to leave? Does his whole family think I'm damned to hell since I don't attend their church? Sorry these are loaded questions but....I'm looking for any sort of insight....please....
