I think this is more than a silent treatment and it is definitely more than the need to be in control. Just the fact that he thinks he can talk to you as the following: "must now take the consequences of your behaviour" is very disrespectful. This is a red flag that should not be ignored.
Please allow me to ask you. Why do you want to be with someone who is intentionally causing you pain? He knows that you are suffering, yet he is choosing to speak to you in the above manner and continues to ignore you. Is this how your soul mate behaves?
You think that your life will be over if he leaves you and that is probably because he has a very dominant personality and has held the control. I really wish you would want to break free from this.
I am sorry but his behavior (and your acceptance of it) is very concerning.
