@Highfivemum You weren’t being unreasonable. In fact, your reaction makes complete sense once you look at the dynamics clearly and without guilt. The core issue isn’t the DNA relative - it’s your friend repeatedly crossing a boundary you’ve already explained and being, well, insensitive.
You and your DB made a thoughtful, mutual decision based on lived experience, trauma, and what protects your wellbeing. That’s not up for public debate, and certainly not for your friend’s new partner, a stranger to your history - to weigh in on as if he has authority.
Your friend didn’t just mention it. She discussed your private trauma with her partner, allowed him to judge your choices, adopted his opinion as if it overrides your own, repeatedly pushed the topic after you said no, made it the only conversation she wanted to have ignoring the emotional impact on you and in doing so ignored your DB’s boundaries too. That’s not support. That’s pressure.
You didn’t end the friendship - you set a boundary. You didn’t say “we’re done.” You said “drop this topic or the friendship can’t continue.”
That’s a perfectly reasonable line when someone keeps dragging you back into trauma you’ve chosen to leave behind. She took it hard because she didn’t expect consequences. But consequences don’t mean cruelty, they mean you’re protecting yourself. Your childhood trauma is not a debate topic. People who haven’t lived through it often underestimate how destabilising it is when someone keeps poking at old wounds “for your own good.” You’re not doubting yourself because you did something wrong - you’re doubting yourself because you’re used to managing other people’s reactions. That’s a trauma response, not a sign you misjudged the situation.
Your DB agreeing with you is important. He lived the same childhood. He understands the stakes. He sees the same pattern. That’s a strong indicator your boundary is reasonable.
What you did was proportionate, protective, and necessary. A 15‑year friendship is meaningful, but it doesn’t give someone the right to override your autonomy or drag you into pain you’ve chosen to leave behind. If she wants the friendship to continue, she simply needs to respect your boundary. That’s not a big ask.
If she is willing to respect your boundary, repairing things is absolutely possible, and it doesn’t require you to reopen trauma or justify anything. The key is to shift the friendship back onto safe, neutral ground while calmly resetting expectations.
You could message her and say something like
“I care about our friendship and I don’t want this to come between us. I reacted strongly because the topic is genuinely painful for me and my DB and I haven't shared everything with you as its too difficult. I can’t talk about my family or the DNA relative. It’s not something I can revisit, and I need you to trust that. When the topic keeps coming up, it drags me back into things I’ve worked hard to move past. That’s why I reacted the way I did. I have told you before I don't want to discuss it but you keep bringing it up. If we can leave that topic behind, I’d really like us to get back to normal. I miss talking about everything else. If it comes up again, I’ll need to step back, but I hope we won’t get to that point.
Then move the conversation to something normal like how her week has been or something you normally chat about.
