My kids aren't the priority

[MrsChuckBass]

I'm in a poly relationship with be gf who also has a bf we all get on etc
I've realised today that my DDs 4&6 aren't a priority with my gf. She has been listing her priorities and how busy she is, time with bfs kids was second on the list; my kids didn't feature
Am I being ridiculous to end things now?

TBH, did you expect a 3 person relationship to be a walk in the park or a relationship of equals?

Are her BF's children her children too?

What did you expect

The relationships won’t be equal, that is why they can take more patience and understanding than monogamous relationships. Inevitably someone will be more loved, more valued than the other. By extension the same would apply to that person’s DC’s.
If poly relationships are for you, you need to make peace with this for your own wellbeing or it will eat you up.
From a mothering POV I’d worry about DC understanding this inequality and being able to accept it without detriment to their self esteem, but only you know your DC.

I’d end it. I don’t think you’re being ridiculous at all to expect your kids to be a priority.
