This is really rough, and it's a huge part of why TRP and RPW (despite being at opposite ends when it comes to sexual strategy; RP men largely having decided to enjoy the decline) are both anti-feminist, but RPW decidedly more so.
Feminist notions about career and delaying marriage have made your situation (along with workforce participation doubling stagnating wages for men!) incredibly common - know that you're hardly the only woman in your situation, partially because of forces outside of your control (when it comes to prevailing wage norms and property expenses)
Since you're married, and because your husband isn't "a boyfriend" or a "significant other" or a "partner" or all the other madeup terms for what aren't committed, final relationships, you're actually still further ahead than most modern women. The average age of marriage is 27. You got married sooner, and are confronting what a great deal of women will be confronting two or more years from now.
Your fertility is nearly over (possibly by 30, almost certainly by 35, definitely by 40), but you are very far away from needing fertility treatments.
It's completely possible you'll be able to have two children, spaced out by a year or two.
So not all hope is lost.
Things you should be doing:
Polishing the sword, refitting the armor, bandaging the wounds
My husband had to deal with a salary cut, then a job search.
I feel like a failure because we're still renting, I have to work to help financially provide for us
I also feel like a lot of this is out of my control
If your husband is even half-decent, I guarantee you this entire situation is killing him.
If you think it's tough to be a woman who doesn't know if she'll have kids in a home soon, try, try to put yourself in the shoes of the man who looks at the woman he loves feeling like her nest is empty as he is unable to change things.
Women and men are two halves of the human whole - just like life evolved the cell nucleus, just like single celled life gave rise to multicellular organisms, so too did sexes evolve to harness the pressure of reproduction selection (sex) and offspring maintenance (what families do) so as to confer further survival advantages to your young.
I'm not trying to distract from your very real, very serious problems with a biology lesson.
I am saying that solving this issue is literally your purpose on this planet.
Your husband is the male in your relationship, his body is built for constant work and effort from now until he's nearly dead. His impulses are that of protecting and providing for you. It is his mission, and if he feels like he is failing in it, it can kill him.
From his perspective, the old rules that he's finally broken back into, by marrying and finding a woman he loves, and not being in the meat grinder, are precious and his role really is to provide.
Would a woman like you date an unemployed guy his age?
So from his perspective, he is betraying and failing you and it makes him miserable and unable to contemplate kids, contemplate a house, and might even make him neglect the day to day of the relationship because his mind is intently focused on the mission of caring for you no matter what
So be his woman in the relationship, and help him out with that.
This is the kind of support men want from women; they want to have their efforts acknowledged, they want to know that she will stay faithful to him, they want to feel like she still looks to him as the anchor in the storm, as the sentry at the gate.
I'm not kidding; sex can help. Sex is you physically indicating he at the genetic level is desirable. The reward pathways that stimulate him to do anything with is life are partly governed by his sexual life. It's just how it is. Way more important, is kindness at home, positive touches and hugs and words - - for him to know that you have faith in his resolve to improve things, for him to know that you think he is the man that will save the day, that he is the one that is going to fight and fight damned hard to do right by the marriage, is enormously important.
Men will literally kill one another over the idea someone's taken that kind of woman from them; it is so much more important to us than you can ever know.
