Make sure your home is secure. Do you have good locks, etc.?
I have two locks on each door. Of course there are windows he could smash and break in, but he lives 4 hours away and is ONLY here when he shows for parenting.
So, I hope he won't be around that much per usual...
I am a little scared of his capacity for doing more than just blustering but I sleep with my phone next to me (carry over from years of his abuse here) and will not hesitate to call 911 if I hear anything odd...
