Partner is addicted to phone, video games, Reddit, Facebook, etc

My partner is so absent. He's not working or in school. He's supposed to be parenting. But he's not. He's physically there but completely ignoring our child. The space is safe but he's always looking at his phone. I wait until our child is sleeping to use mine. I never let it be more important than our kid. My partner complains that our child doesn't love him and I think myself that there's nothing to love when you're just completely ignored. I make the meals. I clean. I work full time. I'm in school online (log in at night) and have a 4.3 GPA. I am on 100% of night duty. I am on 100% of day duty on weekends. I do the drive to preschool for drop off and pick up. Why can't he do anything? He's playing video games all day while we're out. So I come home to a mess. Yes, yes, I got myself into this. I knew he loved video games when I met him. I knew he hated his job. I didn't think he'd quit and then refuse to apply to anything. It's not a gentle parenting specific problem... But how do I get him to participate in any kind of parenting? My child doesn't ask for him because it gets us nowhere. I do all of the bedtime routine, etc. It's not like having no partner because he actively makes such a mess every day. I'm not attracted to him right now because he's so self absorbed with tv and games... He says I need to chill out. But how? He required more parenting than our four year old.
