Out of my element

I fear that my marriage can't survive this one. We have been down this road before, not too long ago and I can't make him see that I will NOT be changing my mind on this. He keeps talking about giving me "time" to think about things, "time" to "decide" how I feel about this. My feelings have been the same since 4/29 and they WILL NOT CHANGE. The safety of my child, of OUR child is my 1st priority. Even the absolute pain of losing you and our family can not shake my resolve in this. Yet, you still can't or won't understand. To me (and I would hope to you) even the .01% chance of harm coming to my child that I could have prevented is too much. The hurt that COULD come to him from this is too much for me.
I feel like my world is burning in front of me and there is no way to extinguish the flames. I want to survive this, want US to survive this, but I just don't know how.
