Brother problem

Su

My brother is the epitome of failure to launch. He is 29. My parents kicked him out at 18 because he was skipping school to play video games and was lying about going to work so he could hang out with friends. Anyway he didn’t pass high school and was homeless for awhile. For the first 3yrs I helped him a lot and he did job corps (thankfully got his GED). Then he ended up moving in with my grandparents. They didn’t charge him rent or really demand much from him. He never really held down a job, not because he’s got a bad personality (he’s got a great personality which is how he is so successful at mooching) but he just wouldn’t go to work.

Ok fast forward 10 years. My grandparents both have died and my brother got 70k that my grandparents had set aside for him to go to college. Since he never did and my grandparents died he just got the money. My husband and I wanted to buy a house so we borrowed 20k from him for a down payment and the plan was he could live with us for a year and a half (since my family is going to sell my grandparents house). Hes used that time to get a job (i pushed SO HARD to help him get a real job - I basically had to do it for him by having him check in with me 3x per week and tell me what jobs he’s applied for). He also has spent all the left over inheritance (don’t ask me how he spent 50k in a year with NO bills).

So now he’s a mailman but they demand he works 12hr days 6 days a week and he hates it. He’s been doing it for about 2 months. He keeps talking about quitting. Today he said he almost quit. He’s supposed to move out in January and he obviously needs a job to pay rent. We’ll give him 5k (of the money we borrowed) in January and pay him back in 5k increments every six months, but he still needs a job to get an apartment.

We’re pregnant with our second kid (bro doesn’t know get) and we are SO DONE with living with him. But now he is talking about quitting and I dunno what to do?! How can I just kick him out? Especially when I can see that his job IS really demanding. What would you do? Help!
