>> “Is she God’s mother? “ <<
Absolutely not!
Yeshua was the Son of God before Yesghua created her (John 1:1)
Let me offer this commentary from the Billy Graham Association re: https://billygraham.org/answer/jesus-was-god-in-human-form/
"... He (Jesus) was both fully human and fully divine (which is why He was called the Son of God). Think of it: God became a man, and that Man was Jesus Christ. As the Bible says, “God was pleased to have all his fullness dwell in him” (Colossians 1:19).
Jesus remains in a human body, albeit glorified/changed, body.
Mary conceived Jesus by the Holy Spirit. Nine months later Jesus was born in Bethlehem. Jesus is not 2 persons. He is not the God Jesus and the human Jesus. He is one person referred to as the God-man. For many in Christiandom it's quite simple. God is Jesus' Father and Mary is His mother. When a woman conceives and gives birth, we refer to her as the mother of the child. Jesus is no exception.
