You will not win. He will never see her behavior as more than "girl stuff". Tell him mean girls are not girl stuff. His daughter has no right to spread rumors at school, criticize everything your daughter does and finally tell her that her Dad wanted your daughter to be more like her and that her Mother only kept her around because she had to. Tell him you actually caught that one. If he cannot remember that he has two children and each needs to be protected, then you need to talk divorce and a parenting plan that protects both girls. Tell him the courts will be involved and he will not be allowed to continue this benign neglect.
I Kicked My Stepdaughter Out — My Daughter Matters More, and I Won’t Apologize

One of our readers shared a story that dives into the painful reality of blended families. She tried to balance being a stepmom with protecting her own daughter. But when tensions between the girls reached a breaking point, she made a decision that shocked everyone — she told her stepdaughter to leave. Her husband accused her of tearing the family apart, yet she insists she did what any mother would do: put her child first.
The letter with her own words

“Hi Bright Side!
When my husband’s 16-year-old daughter, Lily, came to live with us, I hoped we’d build a bond. But over time, she started clashing with my 13-year-old daughter, Emma. She’d make little remarks about her clothes, dismiss her artwork as ‘childish,’ and spread unkind comments at school that left Emma feeling left out and upset.
I asked my husband to step in, but he said, ‘They’ll figure it out, girls fight like this all the time.’ I wanted to believe him — until the night I overheard Lily sneer at Emma, ‘Dad wishes you were more like me. Mom only keeps you around because she has to.’
Emma froze, her eyes full of tears. That was the breaking point. I told Lily to pack her bag and stay with her grandparents for a while. My husband exploded, accusing me of ‘choosing sides’ and ‘destroying the family.’
But I couldn’t stand by and watch Emma be torn apart in her own home.
Weeks later, Lily sent me a message. She wrote, ‘I’m sorry.’
My husband said, ‘See? She admitted she was wrong. Now it’s time Emma apologizes too, so we can move on.’
I was speechless. Emma was the victim — but my husband still wanted her to take some of the blame just to ‘keep the peace.’

Expert tips

Prioritize emotional safety. When a child feels secure and supported at home, it shapes everything. They face new situations with confidence, ask for help when needed, and recover from setbacks more quickly. That foundation of safety fuels focus, strengthens memory, and even helps them form healthier friendships in and out of school.
Set boundaries early. In blended families, clear rules aren’t just guidelines — they’re what keep harmony intact. Boundaries reduce conflict, encourage cooperation, and help everyone feel like part of one team.
Make rules a family project. Sit down together, talk openly, and let everyone have input. When kids help shape the rules, they’re more likely to respect them. Keep expectations SMART — specific, measurable, achievable, relevant, and time-bound — and be clear about consequences. A little structure now can save a lot of heartache later.
Double standards and stepparenting
Many stepparents try to show fairness by holding stepkids to the same rules as their own children. The intention is good — but it can backfire if the kids are used to very different norms in their other household.
What looks like “equal treatment” to you may feel like punishment to them. For example, if dessert has always been a given, suddenly having to “earn it” by finishing vegetables might seem unfair rather than consistent.
Expert tip: In blended families, fairness doesn’t always mean identical rules right away. Start by gradually introducing new expectations, give kids time to adjust, and let the biological parent take the lead on discipline early on. This helps preserve trust while gently creating consistency for everyone.
Lasting family harmony comes not from treating everyone exactly the same, but from making each child feel equally respected, valued, and safe.
