To question this?

My partner has two sons from a previous marriage, I was just having a nosey at the CSA maintenance calculator and found that he is paying nearly double the expected amount.
Now I feel awful writing this as they are lovely kids, I feel like I'm going to get flamed for saying this. I completely support him supporting his children. But we have no savings, no back up, honestly don't think we will manage Christmas this year. We are always waiting for the next payday. Would I be unreasonable to see if it could be lowered?
For background info, we have been together for 7 years and have 1 dc ourselves. EXW dosent work and go on 2 holidays a year (we can't afford 1) partner works full time plus over time and I'm part time as my wage dosent cover childcare for our dc. Like I said I feel awful because this money goes to his children and I know that is so so important I really do, but I do worry if the car breaks down or something we will be screwed.
Am I awful?

Grrrrrrrrr. "Forget about how well she's doing." "How many holidays they go on is irrelevant." BOLLOCKS to that. If a family that can barely make ends meet is paying an amount they can't afford to a family that's living the high life, that is WRONG, and it's so bloody obviously wrong that my blood boils at those who think that the OP is BU.

Erm...yanbu! How can he be paying maintenance for somebody to have luxuries like holidaying twice a year while another of his children is living in a household that often can't pay for essentials like shampoo?!
The children are teens, the mother chooses not to work, you work and are struggling. It's not right. I don't agree with people saying yabu.
It's good to pay for his children, but not if one is now missing out on basics and you're having to borrow money. He needs to get his home in check!
Speak to him.
