I left my father on the side of the road and I feel guilty even though he deserved it
Growing up my father never cared about me. Even when he lived with us he barely bothered to speak to me and he never contributed a cent to my upbringing. After he finally left the only contact I had with him for years was 2 phonecalls a year, on my birthday and Christmas. He refused to ever pay for anything, no clothes or food or school supplies or glasses, nothing. My mother raised me all on her own while he claimed he was a great father because he always remembered my birthday. During those phonecalls, he would promise he would come visit me and bring me my present. In 2 decades, he actually showed up maybe twice and all he did was say everything was my mother's fault and she just wanted to steal his money.
Despite this, my mom insisted that I should try to keep up a relationship with him amd even got made at me for not answering the phone, even though he always claimed she was the one stopping him from seeing me. As I grew up I eventually stopped answering him completely and I went over a decade not seeing him or even thinking of him at all.
Last year he showed up out of the blue to say he had a stroke. After that he started calling me very often and showing up, he'd ask me to have lunch with him and ask about my day and what's going on with my life. He began wanting to have lunch almost every day and eventually started asking me to give him a ride home and to doctor's appointments. I initially agreed to have lunch with him out of pity, but I quickly realized he was looking for someone to take care of him now that he's sick and I cut him off. He was even starting to hint that he hoped to live with me. When he wouldn't leave me alone I blocked his number.
Now months later he showed up at my job demanding an explanation for why I'm not speaking to him. I told him he doesn't deserve to have a daughter to take care of him now that he's sick when he never cared about me when I was a kid who needed him. He bragged during our lunches that he used to go on vacation to France and Cuba, he never once invited me. I pointed out to him how he was enjoying life traveling around while my mom was working herself to the bone to feed me and he had the nerve to say nobody ever asked him for anything. Not only was this a filthy lie he is my father, it's his obligation to contribute, he doesn't need to be asked.
He started crying and begged me to at least give him a ride to the train station. I told him he got himself there, he can find his own way back home and I drove away.
Now I can't stop feeling horribly guilty even though I know I shouldn't, my hands won't stop shaking and I feel like crying. I feel like the bad guy even though I am adamant that I don't owe this man anything. I wish he would just disappear and now I fear he'll keep showing up and making scenes at my workplace. This is making me sick, I can't even eat or think about anything else.
