DW,
I am sorry to say this but I am not at all surprised.
Look, do you and the kids have somewhere else you can stay for awhile.
I, too, think he is a dangerous man.
I used to carry pepper spray...but that wasn't enough.
To tell you the truth, I and a few others here have wound up moving far away.
And keeping our new location a secret except from a select few.
I know you can at least go to the DV shelter.
You really need to be very cautious right now.
Please, better safe than sorry.
