If you do a safe boot, by holding the shift key down when you boot, are you able to log into the main user? Note a safe boot will take longer than a normal boot, which is normal. If you can get into the system via a safe boot, that says that one of that users login items is causing an issue. You can look at those in System Preferences under users.
