Hello! How should I react to my own mother's strong interference in my life? I'm really tired, I don't want to ruin our relationship, but her actions are forcing my hand. By the way, my mom lives 200 km away from us and my husband; she has the opportunity to visit us, but she doesn’t. My husband and I decided not to send our 3-year-old son to kindergarten yet, for our own reasons. This infuriated my mom because we didn't consult her. She wasn't asked, even though I told her that this is our family and she shouldn't interfere. A week later, she calls again, saying that he won't succeed in life, he needs social interaction. You’re probably using him as an excuse not to be pushed to work (although no one is pushing me, and my husband says I should stay at home). For the record, I didn’t go to kindergarten and grew up a reserved person (because my father drank, beat my mom, and she was always looking for him, I had no support). She thinks the reason isn't the parental relationship but rather the lack of kindergarten. Then she said that she found a football club in our city and that he MUST be enrolled. I said, thank you for the information, but I need to discuss it with my husband. And she again asked, why not enroll him there? Why don't you want to? And so on. Recently, she blurted out that she wants to take my grandson to live with her and my stepfather. They would send him to kindergarten and take him to activities, while my husband and I could have another child. I was shocked by these words. She supposedly pities me and wants what’s best. In her opinion, I have no support, I'm alone. But she can't just come and visit, or take him for a couple of days, even if we bring him to her. She also said, let me come to you, and we'll go look at children's clubs. I said, I have a husband, and we can manage on our own. But she said, why distract him from work, let him work. As if he's not a father 🤦 She really started to interfere a lot in our life. Especially when it comes to our child with my husband. What should I do in this situation? My husband and I have a wonderful, trusting relationship. I've never spoken a bad word about him to her.
