I could have written this.
He is mirroring you. It is absolutely frustrating. They adapt your vocabolary and say the exact same sentences as you.
Then you get confused, because your words meant something. Him copying it, cant be right.
Now if you ever mention projection he will start to use that all the time, so dont bring that up.
Thats a way to really start gaslighting you into thinking your opinions are actually his.
Keep firm that they are yours and you felt like that for a reason.
Narcs manipulative so much that you start to question everything about yourself. You will question conversations you have had, because he's now saying they never happen. He will lie to everyone, especially you.
Dont trust them.
