Strangely enough this is exactly how the domestic violence started with my ex husband, he just pinned me down like this out of nowhere and did the same without recording.
What did he expect your dad to think if he saw a man pin his daughter down and being recorded with all the other things like bouncing the bed, surely your dad would see the abuse you should have let him send that! He wouldn’t have sent that but would be good evidence for you to get him charged.
Anyway when I said how it started I mean it got a lot worse, I had many broken bones and traumatised children who are now adults and still dealing with the trauma of seeing and hearing things they shouldn’t have and this went on for 1 year, don’t make the mistake I did and think he will change.
He won’t he will get worse.
