My new wife 'brainwashed' my stepson

I told her that at home, Lan's mother never let me call Ha's mother. If I wanted to call, I had to ask for permission. If I wanted to write a letter, I had to write a draft first and then show it to Lan's mother.

5 years ago, when I was still the director of a media company, I was captivated by her charm with two children. We quickly rushed into each other despite everything. At that time, she had a happy family with two children; so did I. After a year of hiding, everything was revealed, we broke everything we had to "legitimately" come together. A dreamlike wedding took place, we had another child together. However, at the request of my parents, I had to fight for the custody of my son from my ex-wife. To please them, I followed to the end to claim the child (who was also the eldest grandchild of the family). As for my ex-wife, she was in pain, begging me not to separate the two children, but I refused. Sometimes I also thought about my ex-wife for losing everything, but that thought only passed because I had to please many people right now.

My step-son came to live with my family, everything was fine. I was very proud because my new wife always took good care of me and my step-son also seemed to be attached to my wife. But recently, my ex-wife kept calling me to scold me about how my new wife was filling my son's head with wrong thoughts about his birth mother. Not only that, my ex-wife also asked me to leave her alone because my new wife often teased me, texting her about not being able to raise the child.

I thought it was a fabrication by my ex-husband, so I didn’t think twice until one day I witnessed it with my own eyes. That day, I was supposed to go to a meeting but got home early. I went to my step-son’s room and heard my wife telling him to practice writing. My new wife read to my son about his New Year’s wish: “I want Lan to be my real mother” (my new wife’s name is Lan). He hesitated but still wrote. Next to him, my wife sweetly emphasized each word; the essay was no longer his but his new wife’s.

The next day, I asked my son about the situation on the pretext of buying school supplies for my son. After a while, he honestly said that at home, Lan's mother never let him call Ha's mother. If he wanted to call, he had to ask for permission. If he wanted to write a letter, he had to write a draft first and show it to Lan's mother. Only if my wife allowed him to send it to his mother. My new wife also always instilled in my son that his mother did not love him, that he had a new mother, and that his mother had abandoned him. Gradually, in my son's mind, he always thought that his mother did not love him so she left him with his father.

I suddenly feel confused because I don't know what to do now, I really don't want my son to think wrongly about his mother. Although my ex-wife and I no longer have feelings for each other, the truth is she is the one who is disadvantaged. As for my new wife, I don't know who is the real person? I hope you can advise me. Sincerely thank you.
