Help with my partner

My partner and I have been together 5.5 years, lived together for 4 and recently bought a house. He has ADHD and struggles with executive function and it’s affecting our relationship a lot. Almost all of the household load end up in me. I have to explicitly tell him to do anything, even basic things like clean a bathroom, and even then it often won’t get done for days until I reach a breaking point and snap. I often feel like his mother and he’s a 14-year-old. It’s affecting how I feel toward him in general and has created bad habits. Any suggestions?
