Holiday visitation schedule

I know we should seek legal counsel, but it’s very last minute so please bear with me.

My husband and his ex-monster...I mean ex-wife, have a normal visitation pattern that my husband picks his daughter up every other weekend when he gets off work, and she then goes to school on Monday and goes back to her mom from there.

Our holiday schedule says for the thanksgiving holiday “Child will be with father from 12PM on the Saturday vacation starts until 12PM on the day of Thanksgiving”.

My thoughts were that we’d get her tonight at 6, for our regular parenting time, and then the holiday schedule starts tomorrow, in addition to our regular time.

Mom is saying we can’t have her tonight because the holiday schedule starts tomorrow, and won’t let us pick her up! Am I stupid for thinking she’s being a bitch? She never wants to let us have her ANY extra time no matter how much we ask. She wouldn’t even let us get her for her birthday Any because it “wasn’t our weekend”!

Edit to add: We’ve been married 5 years and they’ve been divorced for 7 and half. She is super control freak and has only gotten worse over time. Child is 8 and is very vocal about wanting to spend more time with us, but Mom has yet to cooperate.

Edit #2: I guess i don’t have a solution for today, and that’s ok. We’ll see her tomorrow. I am just becoming more and more frustrated with the legal system and fathers rights! I HAVE a child with another man. And I’d never in my life be so petty as to not let him interact with his child. My husband goes above and beyond to be in his kid’s life and it’s so sad to me that no amount of money he pays or how many times he asks his BM, he can’t spend more time with his child
