Physical & Emotional Abuse Support Group
Abuse is a general term for the treatment of someone that causes some kind of harm (to the abused person, to the abusers themselves, or to someone else) that is unlawful or wrongful. No one deserves abuse, period. Abuse can be emotional, physical, or sexual.
I get the impression you live with your family, so if that's the case then maybe it would be the right time to tell them what happened and why you don't want to ever have to be around that monster again and that you won't, you won't be there when he arrives and you won't return until after he's gone.
If you don't live with your family, you are not obligated to even speak to him, let alone see him. you have a roght to protect yourself and your property. you don't have to answer the door unless you want to let him know he's not welcome on your property and if he ever returns you will call the police.
I can't think of anything more heinous than blaming a child for their parents death. You are not to blame and never were.
I tried for years to tell him, do not stop by, do not drop in to say hi, do not come over period. Do not call me, do not text me, do not stop me in the parking lot at the grocery store to say hi. NO CONTACT! And he wouldn't listen. I tried lying too, can't come in, I have the flu (cough, cough) oh, sorry, I ddin't see you at the store. Nope, my phone isn't working, thanks for stopping by to see if I was ok, please leave now. After he dropped in to visit one time and I found myself running from him wielding a kitchen knife to keep him from touching me, it was my breaking point, I did my research. He's spent two nights in jail, and I haven't heard from him since.
Hope that helps!
Do what is BEST for YOURSELF. You can do it.
