I think BM filed for one of two reasons:

Reason #1: BM watched us have DD and buy a brand new house all in the same year. She knows that I'm a social worker and DH works in IT, so I think she thinks he is the breadwinner, making hefty cash, when in reality, I am the one who made the money moves via my income and an inheritance from my late grandfather. 

Reason #2: Since taking BM to court, she has been more terrified of the courts than usual. She follows the CO to a tee and has been less high conflict than usual. I don't know if she filed out of fear of her lack of daycare and significant pay increase being found out and her being penalized. She willingly turned over all of her financials including her offer letter for her promotion with significant wages and per the report, she did acknowledge that she no longer needs daycare. It just feels weird for her to provide all of that willingly unless she is afraid of getting into legal trouble. 

DH thinks it's #1 more than #2, but this time, it bit her in the ass. 

I told DH that I wish I was a fly on the wall when BM receives the new order. I bet she will flip shit. But I don't know what she would expect since DD is now a factor and BM no longer needs daycare and BM got a hefty promotion. 

DH already fully expects BM to cry "DH is flaking on his responsibilities." The reality is that DH has been paying max CS based on his income for the past 10.5 years. He has never ever missed a payment, even during downsizing and COVID layoffs. He worked 3 jobs in college while going to school full time to fulfill his obligations. We have watched DH's CS increase with every review request BM has made and she has appealed twice before, seeking several hundreds more despite receiving an increase, claiming that DH has the "potential" to earn significantly more if only he applied himself. DH has also paid every single medical reimbursement well within the 28 day requirement. DH has also never missed a visitation and never missed a phone call (twice per week with SS). DH has completely fulfilled his legal and parental responsibilities as permitted by their CO and within what BM will allow and has for SS' entire life. BM loves to pull the deadbeat Dad card that does absolutely nothing and has spread this narrative to every teacher, doctor, sports coach, and friend's parent who will listen, but it couldn't be further from the truth. Unfortunately, the courts have given BM (and therefore her GF), SS to raise, giving BM her ultimate goal. BM wants to raise SS as a perfect family with her GF, using DH as only a sperm donor and slowly eliminating him from SS' life. We have 7 years left of legal obligation and plan to continue our current path until SS no longer wants it. It sucks but luckily, we know the truth. 

It's sad because many of these HCBMs claim their exes to be deadbeat Dads, when in reality, they are keeping the children away and preventing these men from being parents. Our BM should be grateful she isn't dealing with one of those actual deadbeat Dads who never pays CS and dodges responsibility at every turn. I know BMs who would kill to coparent with our DHs. 

We already have an investment custodial account for DD. It was important to me to set her up for success in whatever she wants to do in adulthood - college, buy a house, start a business, etc. 

DH is going to either put the $125 into his retirement to help boost that or into our savings.

I know that my income will never factor into CS. I also know that in our state, BM can only request a review every 3 years. I just meant that we have been living paycheck to paycheck for a while, so having a slight reduction and both of us getting raises will help us get financially ahead for once.
