We don't know her reason for not giving him the address.
My H does not know where i live, and this is because I wont be able to sleep at night knowing he can turn up here in anger (provoked or unprovoked) and start making a scene and breaking things (which he did when he got angry). Although, he never really tried to find out where we live.
So, please, don't be too quick to blame her. It may be a security thing with her too.
Just saying...
