I too am in a one-sided faith marriage. I am christian, was brought up going to sunday school, and then church.
My ex-boyfriend was totally against it all, and as a result of being young and so called in-love I let my faith take a back seat.
With my current DH, he respects my faith, we have had the girls christened and their god-parents (my brother and SIL) are regular church goers and do their best by them.
For me, the girls are too young to understand yet (2.5 and 1.1) so I only take them at christmas time. They have numerous bibles and bible story books, but they still dont get it.
I will take Jessica to Sunday school next september once she turns 3 - the lowest age they take them, but not before.
I wish I could get to church more than I do, but with 2 little ones at home, and being an Army family, its not easy to find a decent church. The one church I do attend is and has been "my church" since I was 5yrs old but is 30 miles away.
DH supports me 110% with bringing the girls up in a christian family. He may not agree with my beliefs, but respect is a big factor.
I will be taking the girls to the christmas services over the next few weeks (will be staying at my dads so easy to do) and DH will stay home with my Dad and do xmas preperations, it works for us at the moment.
After christmas, I have also committed to helping at the church run youth club, and when I finally manage to move back to Ipswich, I will also help with the Boys Brigade on a tuesday night.
DH supports this, and without his backing, Im not sure where we would be.
