Anyone else’s SO not pulling their weight around the house!

I feel like I’m constantly doing more around the house - cooking, cleaning, and cleaning up after my SO, and I’m so exhausted! I end up doing everything while he just lies around doing nothing, which he says is ‘relaxing’. My standards are definitely higher, it really bothers me when the house isn’t clean and tidy. When I ask him to do something to help around the house, he says he will, but takes too long to do it so I just end up doing it myself. Maybe I need to let go a bit, but find it hard! Can anyone else relate?
