The Father exists in eternity, always.
He never experienced time.
The Son, however, entered time, (which he created anyway, and personally defines it, being called the beginning and the ending).

He entered time in the incarnation, and experienced time as we do.

Yet, somehow, even though he was experiencing time, he still somehow was experiencing eternity also:

John 3:13 And no man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven.

John 8:58 Jesus said unto them, Verily, verily, I say unto you, Before Abraham was, I am.

Although, for lack of any better words to describe it, the focus of his person was in time on earth?
So, the experience of the relationship between the Father and the Son was somehow different, due to the incarnation.

Not only was the Son in time, but Jesus was fully God and fully man.

So the relationship was the Father in eternity with Jesus the God-man in time on earth.

This was a very different experience for the Father and the Som.
Then, what was the relationship like for both the Father and Jesus, while Jesus was on the cross?

Matthew 27:46 And about the ninth hour Jesus cried with a loud voice, saying, Eli, Eli, lama sabachthani? that is to say, My God, my God, why hast thou forsaken me?

Then what was the relationship like as Jesus died?

Jesus commended his spirit into the Father's hands and gave up the ghost.

His soul went into the lower parts of the earth, and his body was laid in the tomb.
There is another question regarding while he was dead for those three days and three nights:

Was Jesus' soul and spirit still in time?

Or was his soul and spirit yet in some other kind of dimension, different from eternity, and different from time?

If so, what was the relationship like with the Father and the Son, between the cross and the resurrection?
