I’m confused

I’ve been with my s/o for 4 years, he was my first love. We have an 11 month old. Since living together almost everything about him just annoys me. I want things to work but then we continue to fall in this repetitive cycle of arguing & Not talking for a few days. I always have to tell him how and when to do things around the house. He doesn’t like being treated like a boy but doesn’t do certain things unless told to. I have to repeat myself multiple times on how I want things done or how I want my space respected. Always leaving things everywhere as if it doesn’t have a place. Feels like I have two little boys. After two times you should know to throw out the garbage when it’s full, after two times you should understand I need my space when upset. It feels like we’re two complete different people and we’re not the same ones we needed before. Im not sure if I don’t like him anymore or we actually belong and we’re just not doing things right . Do I sound crazy? Am I wrong? I need different perspectives.
