I am curious as to why no one, not even police who cuffed you in front of these precious babies, did not ask the children what happened? They were left behind with dad, I presume, while you had to go to jail? I cannot imagine how they wont be called to answer in court, if you decide to press charges. children can be questioned in my state, tho it might be in judges chambers, in order to spare them extensive anxiety. I dont know how the anxiety of being questioned could be worse than seeing your own father attack your mom in front of your eyes.
I am so sorry wtbh. this has been going on for much too long for you and the girls. Prayers that things are resolved, and that he gets his punishment for this horrendous stuff. i do like the idea of putting a hidden camera at entrances. you could surely use that in court!
wishing your and your girls peace and safety.
