Should I let him pay less child support?

So my soon to be ex-husband wanted out of our marriage last year. We are filing for divorce soon. We have a toddler and we have a Child support order that is notarized privately, nothing through the court yet. When he moved out he got a “luxury” one bedroom apartment (which is over half of his paycheck). I leased a two bedroom apartment, that is still nice but much more budget friendly. He pays about $300 more in rent than I do. Our daughter lives with me and he has visits with her a few times a week. He pays me child support every month without issue. The child support covers his half of daycare, food, and necessities for our daughter. 

Before we moved out, I questioned him on how much money he was spending on rent and that it might be too of his budget. I always managed our money so I know how it breaks down. I even laid a budget to show him that rent was too much and he insisted he was fine even when I showed him he’d be in the red every month. I pay less in rent than he does, but I also have a commute (he has a work car) and expenses that still make my budget tight.

We were FaceTiming today so he could talk to our daughter, he let me know that his car is about to break down and has a lot of repairs that are needed. The car is been paid off for a while so getting a new car means adding a car payment.

He kept hinting to the fact that he doesn’t have money month to month and said adding a car payment will break him.

We are filing for divorce this summer and I’m trying to be cautious of how things will affect proceedings. I also don’t want to be an asshole. I’m certainly not rolling in it and am on a tight budget too.

He hasn’t asked yet… But I know him so well that I know that it’s coming.

If he asks me to let him not pay as much in child support for a few months, should I let him? Or would that screw me when we go to court because I allowed him to pay less?
