He wants as well to make his point that there is no way he'll get back with you.
He simply exaggerates to stress this fact.
When you step out of a relationship, the past might feel like a dream. When you are out of the context, it can be difficult to recall emotions and feelings.
The love you shared was real no matter what he says.
The moments you had together were valuable for you and him at that time.
Again, the only reason he says these things is because he wants to create space in his mind and life so that he can start over.
It comes from a natural need to free himself from any regret which could hold him back.
