These are good tips for a healthy relationship. As you say, what matters is to know the real person and not the one we idealize, as well as to establish good practices such as effective communication, mutual respect, giving each other space to be individuals as well as a couple... among many other important aspects.
If we are not satisfied and we do not find a solution, the best thing to do is not to wait for him/her to change, but to seek professional help if necessary.
Greetings, have a nice day 🌻
