Good for you. Although we can sit around and plan and plan how things are going to play out, often God has another idea and His ideas are always better than anything we can come up with on our own.
Enjoy your peace. Enjoy your baby. Consider a restraining order if he comes back with more threats, or even apologies. He most likely will be back and you need to be ready. This is probably not over yet (though we all pray that it is).
Have a serene weekend!
