Well eventually she’ll have to have some separation as she will have to go to school.

Her bed could be in the same room. Not even suggesting separate bedroom. I get it that now it’s not on the agenda and you aren’t even leaving now. If you decide to leave at any point, she’d be trained to sleep in her own bed by then and sleeping with dad will be unnecessary. Eventually everyone sleeps in their own bed. It can’t possibly go on forever.
