That’s a really sensitive situation, and the core of it is actually something healthy: respecting consent and boundaries even when you want to help.
Here’s a clearer, more natural way to express your sentence:
“She asked me not to be in the delivery room, even though I wanted to support her, so I respected her wishes and stayed outside.”
If you want a more emotional or reflective version:
“I wanted to be there to support her in the delivery room, but she asked me not to come in. As much as it hurt, I respected her decision.”
Or a more storytelling style:
“I stood close, ready to support her, but she asked me not to enter the delivery room. I didn’t understand it at first, but I respected her wishes.”
If you want, I can help you turn this into a full story or dialogue scene.
