Cant breathe through one side of my nose ever. Is there something wrong with my anatomy?

Turbinates. You are 48 years old and cannot breath through one of your nostrils. Having an ENT doctor look at your nose will help. You could have a swelling of tissue inside that prevents air movement. It obviously bothers you some but not that much. You may benefit from a study called a ct scan. It along with a ENT doctor should help.
