NDad keeps trying to reach out, at my limit with my mom

I've been NC with my dad for 5 years, minus a few attempts to bridge the gap us.

Last May my sister graduated from army training and my mom and I went to watch, knowing he would be there. In the course of 3 hours he told my mother to kill herself, to walk into traffic to kill herself, and then insulted my weight. He hit a parked car on his way out from dinner, and I told my mom I was done.

At the actual graduation he elbowed my mother in the face, told me that my presence ruined the event, and then sent his gin soaked girlfriend covered in body glitter to try and make the peace.

Sorry, not girlfriend- tennant that he fucks when he can't pick someone up at the bar.

I haven't spoken with him since, and I won't for the rest of his fucking life.

He's trying to weasel his way back in my life through my mom, applying pressure through her relationship with my sister.

Basically I told my mother I'm done caring about her relationship with my sister. I don't fucking care. I don't want to hear his name ever again, and stop referring to me as his daughter.

She's at a loss because she doesn't want me to regret this after he's dead.

I told her that everyone has regrets when their parents die, and frankly, it'd be better if he kicked it tomorrow because then I could heal without him gouging my fucking wounds. Then she started crying and like...

I'm not a monster, am I? I just...I don't fucking care. I hope whatever health scare he wants to hint that he has is worse than expected. Hope it's painful when he goes. Hell, I hope that one of his girlfriends kills him.

I'm wearing red to his funeral and I plan on thoroughly wrecking it and showing my figurative ass- he deserves every bit of it.
