Bio Mum Keeps Posting on X
I’m looking for some advice on a situation that’s becoming really upsetting for our family.
I’ve been with my partner for 8 years, and I’m stepmum to his two kids (F21 and M17). Their parents divorced after their mum had an affair. Over time, both kids ended up living with us—my stepdaughter moved in at 16, and my stepson was dropped off at our door at 14 when his mum remarried and didn’t want him living with her.
My stepdaughter no longer has contact with her mum. My stepson didn’t speak to her for a while either, but recently she’s started rebuilding a relationship with him. The issue is, she tends to be very manipulative and asks a lot of questions about what’s going on in our household.
We had asked him not to share private family matters with her, and we thought he understood. However, we’ve now discovered that she’s been posting on X (Twitter) about our lives—sharing personal information and making negative comments about their dad.
This has really upset my stepdaughter, who feels completely betrayed by her brother. It’s also causing a lot of tension in the house.
I understand he’s 17 and probably wants a relationship with his mum, but the impact of what he’s sharing is hurting everyone else.
Has anyone dealt with something similar? How do we handle this without pushing him away, but still protecting our family’s privacy?
Edit: SD has now spoken up and shown her brother the posts. She’s really upset with him for oversharing, especially since she had already asked him not to tell their mum anything about her life.
I also spoke with SD and told her it’s best not to read what her mum is posting. It’s upsetting, and her mum continues to share things about our lives publicly for attention, despite the impact it has on the kids.
From my side, I’m also upset about the negative comments their mum continues to make about their dad, and the way she twists situations to paint herself as the victim when she was the one to choose her partner over the kids twice.
I feel really sad for my SS, as it sometimes seems like her interest in him isn’t genuine and may be more about her own needs, which is hard to watch.
