He said, ’everything will increase now, domestic violence will increase.”
Now he has said, I love you. To death.
OP his threats are escalating, he threatened to kill you, now he has pulled out a knife, he laughed at the end.” He must think it’s frigging hilarious to threaten you after you hug him and tell him you love him.
He wasn’t joking, he was putting fear into you when he pulled out the knife. He sounds quite mad, your children must be on edge all the time. Your children are in danger, you are going to have to be very brave. The Coronavirus is not going to just take a few weeks, you could be with him for months.
You could take your phone while he is asleep and go outside and phone the police. Send them this thread OP. At the very least phone them so they know you are frightened. They will at least be aware you are experiencing domestic violence. They will be aware you are frightened if your voice is shaking.
You poor thing, I wish we could all help you.
