You need to read about Arianism which you are espousing.
God is fully God while also being fully Man.
As a part of mankind he was developed in His Mothers womb for nine months and she then gave birth and nursed her Son.
Mary was Jesus human Mother therefore she can be properly called “The Mother of God”.
To not be able to call her that would be to deny His humanity thus you would be guilty of the Arian heresy.

Oh? You're saying that the second person of the Godhead is a created being? Really? Isn't that some kind of heresy or other?
Or are you saying the Holy Spirit got it wrong when He breathed out *mother of Jesus* in Scripture?
Or perhaps, since Catholics like to take credit for the Catholic church writing the Bible, the Catholic church got it wrong initially by calling Mary *the mother of Jesus*.
What else did they get wrong then?
To not be able to call her that would be to deny His humanity thus you would be guilty of the Arian heresy.
Calling her *Mother of GOD* denies the humanity of Jesus.
