Is your DH paying more than the state/territory-calculated amount? Did his income change due to his own choices, or was he let go and this is the best he could do?

If he is paying over the state-calculated cost (your area should have a free calculator online for you to use), then he could request a modification down to that level. However, if he purposefully took a lower-paying job or switched to a lower-paying career, a court will likely not lower his CS requirement because he has the ability to make more.

While many places still lag way behind regarding custody arrangements, it appears that many places are tightening up CS requirements so that one parent doesn't get taken o the cleaners just because the other wants more money. Many places now seem to calculate CS and order just that, then let parents fight it out in the CO what other financial contributions will look like.

It's worth it to explore. In the meantime, can one of you get a second job? Not ideal, of course, but it would help push you all through for the time being. Or maybe look for a higher-paying job.

If your Dh's income has changed, he may be able to get his CS order changed. As you are in TX, they use a pretty well set guideline (something like 20% 1 kid, 25% two kids). It is based solely on the NCP income. 

While $1,000 may sound like bunches, it would have been the norm in your state per your state's laws/guidelines and your DH's income. Again, if the income on his part has went down due to circumstances beyond his control (such as loss of hours at work, lay-off then job change from necessity blah blah), try a modification. 

Unfortunately, BM's income (or lack of one) does not count. Neither does her new guy's mega bucks. With BM having the children all but EOWE, the state assumes she does her share of supporting the children. She feeds them and shelters them upwards of 26 days a month. Her new guy is in no way responsible legally for financially supporting children that are not his. 

Why it sucks that your household seems to be struggling so harshly, short of being able to modify due to genuine reasons, your state is not going to lower CS just because your trashy BM manged to land herself some rich old dude. And changing custody to get out of CS isn't usually something courts approve of. Would $1,000 a month really so vastly improve your current situation so much that your husband could afford a three bedroom home (along with whatever expenses come with owning a home)? 

Not trying to be unsympathetic , life is hard when one is struggling to make ends meet and situations as you write can build real resentment. You will read many different members here with their stories of how they are ending up supplementing much of their household's expenses because their husband/SO/BF is paying CS plus whatever bills he brought into the new relationship.... so you will find many members who know exactly what boat you're sitting in and how hard (both physically and emotionally) that it is. 

My oldest son's first wife dumped him for the boss. Yep, the company owner with the big bucks. However, it is my ex-DIL and my ODS who financially carry the load of support my GS. While GS's SF has been quite good to my GS, anything GS gets from the SF financially is a 'gift' and because SF wants to. 

Your profile picture says it all: accept what you cannot change and change what you can. As the ladies above said, your H may be eligible for a modification, so I'd definitely look into that.

Would you feel differently if you knew every penny of the $1000 was going towards skids and BM's shopping trips were fully funded by her husband? Does BM work?

What does CS and BM's husband's income have to do with one another?

As long as the amount of CS being paid is not more than what the state requires, mom isn't doing anything wrong.

Im sorry for you, this must be very hard to live with. Sadly, we cannot do anything about what a bm spends cs on. It makes you sick i know.  

I cant help with any practical advice as the system here is different but i hope that maybe some of what others have said will be helpful. Keep your chin up. *hugs*

 The best thing you can do for yourself stop being jealous of them.

It sounds like she gives them a lovely lifestyle and the child support is spent on them. Sounds like they do a lot of fun activities as well as have a roof over their head, food in their stomachs, and nice clothes to wear. Your husband should be happy his kids are taken care of. Her husband‘s income is none of your concern. While I know it sucks to struggle, it’s worse to spend your time being jealous of others.
