Welcome mand63, that's a real shame.
In my old cong there was a married couple, she was JW, he was Catholic (still are I believe). They were both regularly invited to social occasions by each other's friends, barbecues, picnics, parties etc . He was happy mixing with her JW friends though he never came with her to the hall and she was happy mixing with his catholic friends, though she never went to his church. Both were very active doing things for their own religion. They had and still have a very happy marriage. We personally got to know him quite well, he was a really nice guy.
It shouldn't have to be the way it is for you!
