How do I handle religious differences with my ex?

Dear Dan,

So, my son’s father was remarried a few weeks ago. The new wife is VERY religious, and my son’s dad is becoming a lot more religious than I ever knew him to be. I am not against this, I am open to them teaching my son different and new things… but with me being not religious at ALL (spiritual, yes) it has caused a few issues.

The main one was recently was when my son came home and told me that “C” (the new wife) told him that God made him, and I had nothing to do with that process since I was un-wed. My son is 4 and I was kinda dumb-founded when he told me this and I really didn’t know what to say (although I wanted to say a few choice things to this woman). I don’t know how to handle it and I am not sure what to say to my son. I don’t want this woman filling his head with these kinds of things either. Help!!!

Thanks, Non-Religious Mom
