Help!

So I asked someone to be the god parent of my child before talking to my so about it and he didn't agree. This was months ago and now we have decided on someone mutually and now I feel obligated to tell the other person that they aren't the god mother. She is one of my good friends and I don't know how to go about it. Any suggestions? I know I shouldn't have asked without talking to my so about it first.
