What would you do?

My husband pulled me aside a few weeks ago and told me we are struggling financially, I’ve been aware of this, but my husband told me he could no longer cover any type of cost I may have(I’ve been a STAHM). But he finally asked me to get a job. So I’m working part time. Anyways My husbands uncle a while back asked my husband if he could stay with us for a bit and if he could work with my husband to save up some money. My husband agreed and let him stay with us. I’ve told him that after the first month he should charge him rent. Since they’d be earning a good amount. I’ve been persistent about it, and my husband has always said no. So I understand why he would hide this next bit of information from me.... well they’ve been working from 8am-8pm. All day. I hardly see my husband, and when I do he’s exhausted. He eats, showers, and goes to sleep. It’s truly depressing. Today we went to the grocery store at 10pm and I don’t know if it’s because he’s so stressed, or if he needed to vent. But he told me his uncle hasn’t been doing that good of a job at work. My husband gives him nearly half of what he earns so that his uncle can “help speed up the job”. They install kitchens and cabinets in soon to be rented apartments.. His uncle is 60+ My husband installs the kitchens while his uncle does the details of the ones he’s installed like level doors and put handles, he’s supposed to finish by the time my husband moves to the next but my husband says he’s been basically installing whole kitchens alone including detailing. Then he feels an obligation to pay his uncle half because his uncle tells him it’s not fair if he doesn’t pay him for a day. So essentially, he’s doing most of the work and giving away like 35%-40% of his check. After this I kind of want him to go. He’s not helping at all, like my husband told me he’d be. Now I want him gone more than ever.
