He’s got you by the short and curlies. Your confusion is being caused by him and it is nothing you have said or done. You are emphatically not going mad. This is exactly what he wants you to feel like. There is no ‘normal’ I’m afraid. At least for you. For him, this behaviour is normal and it will get worse. You probably already know that.
Baby steps and you can start untying the knots of your relationship and you will begin to see him in a clearer light. Keep a diary of all this kind of behaviour. Anything that gets to you or that you notice. One day you will look back at it and wonder how you put up with it. You will also be able to hand it over to whoever is helping you.
