Cutting off my Dad bc he's an addict.

Since 2020 my dad(56) has been in and out of prison/jail. This wasn't his first time he was in jail a bit when I was a child. I'm 27 now. I tried to stand by his side because I felt my parents divorce in 2020 pushed him over the edge into hard drgs. (Thanks to therapy and reflection i no longer believe any of that) in January of 2024 he was put in a halfway house 30 minutes from my house. He would call daily and that was never a problem until he asked for things every time he called. Money, smokes, a phon, more clothes or soap(specific brands only) ect. It just kept happening. I got overwhelmed and it was at this point I wrote him a letter dropped him off some basic necessities and left. I asked him to leave me be until he can apologize for all the damage he did while on drgs or when in withdrawal. How he treated me as a atm and a free for all store. How no matter how bad I had it he has it worse because he's in prison. Always talked down like my feelings never mattered. My problems never mattered to him. I'm was a single mom in school and working full time. I had to cut him off. And I felt better about it. But every 3 months like clockwork he somehow tries to get ahold of me or check on me. Or he calls my partner. We never anwaer or respond but everytime it happens I just feel like shit. I finally put all the damage I could behind me and he brings it right back. I don't know what else I can do at this point. I asked him to leave us alone until I'm ready to talk to him again. But I don't think I ever will be. He's not my dad anymore. Not since he got hooked. I just can't help be feel like shit. Has anyone else ever felt like this in any aspect cutting off a parent?
