1 (32F) share custody of my 5-year-old daughter, Lily, with my ex-husband, Mark (35M). Mark and I have been divorced for about three years now, and things have been mostly amicable.

He recently started dating someone new, Emma (28F), and from what I’ve seen and heard, she’s been great with Lily. My 5 Y.O. daughter often has sleepovers at her dad’s house He has a new girlfriend, Emma, and they seem to get along well. I have always thought they have a wonderful bond. They build forts, read stories, and my daughter often talks

about how much fun she has with Emma. My daughter always comes home happy and excited about her time there. But today, something felt off. Lily was playing with her dolls in the living room when she casually said, “Emma used a sponge to scrub my back, and she said I should sit still so I don’t slip.” I froze. Bathing my daughter? Emma was bathing my daughter? Mark has always been hands-on as a dad, and l’ve never had a problem with him handling baths or bedtime routines. But having his girlfriend do it? That felt… different. I didn’t like it, and I couldn’t shake the discomfort. tried to stay calm and asked Lily gently, “Did Daddy help you with your bath, too?” She looked up and said, “No, Daddy was cooking dinner. Emma helped me because I got paint on my arms and legs.” This didn’t sit right with me.

I understand accidents happen, but shouldn’t Mark have handled it? Emma isn’t Lily’s parent, and it felt too personal for her to be involved in
something like that. I called Mark immediately and said, “Hey, can we talk? Lily mentioned something that’s been bothering me.”
He sounded confused but agreed.
“Sure. what’s up?” “Why is Emma giving Lily baths?” I asked bluntly.

There was a pause before he answered. “What’s the big deal? She’s great with Lily, and I trust her. Lily spilled paint everywhere, and I was busy cooking. It wasn’t a big thing.” “It is a big thing to me,” I snapped. “That’s a boundary I’m not comfortable with. She’s not Lily’s mom.”

Mark sighed, clearly annoyed. “Emma loves Lily and treats her like her own. You’re overreacting. It’s just a bath.” “No,” I countered, “it’s about boundaries. That’s something you should have handled as her dad.” The call ended tensely, but I wasn’t done. Later that day, I decided to talk to Emma directly.

I invited her for coffee, hoping for a calm conversation. But when I brought up the bath, her response floored me. “I didn’t think it would be an issue,” she said, looking genuinely surprised. “I was just trying to help. Lily didnt seem uncomfortable “I’m not accusing you of anything, I said, trying to keep my voice steady. “But I don’t feel it’s appropriate for you to bathe her. That’s Mark’s responsibility as her parent.

Emma nodded but then added, “I respect your feelings, but I feel like you’re making me out to be some kind of villain here. I love Lily, and I’d never do anything to harm her.” The conversation ended awkwardly. Now, Mark is upset with me for “blowing this out of proportion,” and Emma is distant, probably hurt. Was I wrong for setting this boundary, or did overstep?
