Frustrated, looking for tips

Hello all,

Just looking for some tips from others here who have a similar experience.

My bf has a child, 3. They are here every weekend. They take up alot of his time and attention, which is understandable since they're so young, but sometimes I feel this could be mitigated with rules and boundaries set.

They want to play constantly, and do so up until bed time, which I feel keeps them wound up and thus unable to go to sleep. There's no set bedtime routine, which I've brought up in the past that I feel this could be beneficial, but nothings been done.

This leads to him having to lay in bed with them, they want a snack, juice, whatever. He puts a movie or show on every night while they're in bed which I also feel keeps them awake, but he feels it helps them sleep.

I end up spending alot of the night alone, then when he does come out he ends up falling asleep shortly after. It's starting to irritate me and I feel bad I feel this way but I don't know how to navigate it without feeling this way. I feel we don't have any quality time alone together when the child is here, and it being every weekend is wearing on me.

Any suggestions or tips on how others are handing a similar situation would be appreciated.

Thank you
