I am sure the term was not one of disrespect, however, He did use the term 'mother' when He turned her over to John.
So, the fact that during His ministry He never addresses her as such shows that their relationship had changed.
He made that very clear when He was told that His mother and brothers were seeking Him and He stated that His 'mother and brothers' were those who followed Him.(Matt.12:48-50)
I believe your answer to be a non-sequitur to your original post about Jesus calling his mother “woman”.
Also, it should be very clear to anyone who takes the time to really understand and apply the teachings of Jesus, that His mother was obviously the first to show the way of following Him—from her assent to the message of the angel, and throughout all the “hidden” 30 years of his life with her and Joseph in Nazareth.
Please note that she followed him during his public life as well—including being at Cana; also she was along the Way of the Cross and stood at the foot of the Cross. She was in the Upper Room at Pentecost.
There is no reason whatsoever to downgrade any part of her presence in the public existence of the Lord. One of the Seven Last Words of the Lord from the Cross were to Mary and to John the Beloved. He gave them to each other and in that more-than-symbolic action He gave her to all of us, and all of us to her.
We do not now know that, because we were not there at every instance that He addressed His mother, nor has every instance of Him addressing His mother during His ministry been recorded. In other words, you may call your mother one name during your private moments with her, and something else entirely in a public situation. All cultures have instances of that.
You do not know that.
