AITA for not being more involved in my aging dad’s life?

Backstory: my parents split when I was five, and I was mostly raised by my mom and stepdad in the Midwest. My biological dad was the classic “Disneyland Dad” popping in for Christmas or the occasional summer vacation. Our relationship had always been friendly but distant. He moved around a lot for work, which didn’t help.

Fast forward: my mom passed away 10 years ago, and I moved closer to where my dad lives to reconnect with this side of the family. While we’ve had some good moments, it’s still largely a one sided affair. He’s always been like this, low effort, not just with me but in all his relationships. Past girlfriends have even confided in me about his self centered nature.

Now he’s 70, retired, and not in the best shape, health or finances. He lost his license due to too many duis and blew all his money living a boozy, harley bikers lifestyle. He’s now living in a guest house at my cousin’s property, while I’m five miles out. I check in weekly by phone and visit biweekly, but it feels like if I don’t make the effort, there’d be no contact. He’s the type to not plan or prioritize relationships, always has an excuse for why he can’t make it on time, and is notoriously stubborn about accepting help, like seeing a doctor.

My cousin’s family, who he lives with, thinks I should be doing more. But honestly, my whole adult life it’s been me reaching out to him. I feel like I’m already stretching myself for someone who doesn’t reciprocate the effort. So, am I the asshole for not pushing harder in a relationship that’s always been this way?
