Dear Mejo,
No, no, no you don't! You did the right thing by alerting the police department that you had been attacked, violated. This shows courage. He sounds like a loser to hurt you, and to have the children realize what he is. Don't let him convince you of backing away from this.
You can't anyway, the police will charge him and he will be held accountable, which is what should happen. You might have even done him a favor...going to jail/prison will keep you safe and might get him sober or at least away from his DOC.
For right now, BLOCK HIM, no contact, keep you and your family safe. Let the police and lawyers do the talking. Do not speak to him, his friends or his family,ok?
I'm so sorry this is happening to you. We are here for you, lean on US right now!
I will say huge prayers for you but for right now, here's a BIG gentle hug!
TF
