Then the soldiers, when they had crucified Jesus, took his garments, and made four parts, to every soldier a part; and also his coat: now the coat was without seam, woven from the top throughout. They said therefore among themselves, Let us not rend it, but cast lots for it, whose it shall be: that the scripture might be fulfilled, which saith, They parted my raiment among them, and for my vesture they did cast lots. These things therefore the soldiers did. Now there stood by the cross of Jesus his mother, and his mother's sister, Mary the wife of Cleophas, and Mary Magdalene. When Jesus therefore saw his mother, and the disciple standing by, whom he loved, he saith unto his mother, Woman, behold thy son! Then saith he to the disciple, Behold thy mother! And from that hour that disciple took her unto his own home.
I write not these things to shame you, but as my beloved sons I warn you. For though ye have ten thousand instructors in Christ, yet have ye not many fathers: for in Christ Jesus I have begotten you through the gospel. Wherefore I beseech you, be ye followers of me. For this cause have I sent unto you Timotheus, who is my beloved son, and faithful in the Lord, who shall bring you into remembrance of my ways which be in Christ, as I teach every where in every church. Now some are puffed up, as though I would not come to you. But I will come to you shortly, if the Lord will, and will know, not the speech of them which are puffed up, but the power. For the kingdom of God is not in word, but in power. What will ye? shall I come unto you with a rod, or in love, and in the spirit of meekness?

It’s pretty simple, Jesus told Mary to accept John as his replacement, and assigned John to look after his mother in his stead.
You need a verse where Jesus Christ and/or his apostles specifically say that Mary is to be ‘spiritual mother’ to believers. The apostles don’t even mention her by name in any of the epistles.
The Lord is wise. He didn’t address her as ‘mother’ while on the cross (or any other time in the scriptures). As it was, He knew people would be trying to make a goddess out of her.
