S.,
I grew up with the 'Daddy just doesn't go to Church' kind of Catholic Family and it was odd. We went to church with Mom almost every Sunday, and my Dad never came. He left it up to my Mom and that was just how we did things. But, now that I look back on it, it would have been nice to know about my Dad's religious background as a child. He was raised, Christian Lutherin and never talked about it with us until we were older...
So, I guess the point to my rambling is if your husband is willing to go to Temple and put aside any misgivings he has about Judaism and even learn more about your beliefs...why can't you do the same?
My Uncle married a very Jewish AWESOME lady, and my Aunt and Uncle raised their girls Jewish and he even converted. For them, I and the rest of the Catholic Brood always go to major events at Temple and do what we can to support their beliefs within our family.
I think it's important that kids have some kind of belief structure, but today I am a Catholic who is more spiritual than religious...it's just about faith for me and not about where I pray.
If you want your kids to be able to choose for themselves they need to be presented with even spectrums of both sets of beliefs. I think it's only fair that if your husband is pulling his side of the bargain, and attending Temple and learning about your beliefs it's only right to do the same. Otherwise, you might want to put this on the backburner until you can come to an agreement on how to do it.
Good Luck!
