Should I let him keep living with me?

I need help with something. I’m only 20, but I’m married with 2 kids. My brother is 24, has been a drug addict and an alcoholic for as long as I can remember. A few months ago he went to jail for beating him ex girlfriend so bad that she could have died. He was on drugs that night. Since then, he does no drugs, only smokes weed.

We let him move in about 2 weeks ago. My husband got him a job and we set rules for our house. Absolutely no drugs and if he shows any violence he will be homeless. If he doesn’t keep the job, he will be kicked out as well and has to pay rent. So far it’s been pretty good.

However, he’s still an alcoholic. He doesn’t want to get help, he doesn’t see it as a problem. He’s not a violent drunk. He acts more normal when he’s drunk. But in the matter of two days, he spent over $100 on weed, alcohol and cigarettes.

He hasn’t brushed his teeth since he was 16. (Literally🤮) but you can’t even tell. He says he doesn’t because it makes his teeth look gross (lie but okay)

Here’s where the real problem is. He hasn’t drank in one day. Not even 24 hours and he’s going through very bad withdrawals and he can’t wait until he can drink again tomorrow (his part time gives him free drinks)

I don’t like this because my husband got him a job making about $500 a week. $400 a week after he pays us. And he’s going to blow it all on drinks.

That’s extremely irresponsible. Should I just continue letting him live with us if he pays us and stay out of his business about where his money goes?

I will say this, although he drinks every night, he’s never “drunk” he acts more normal while drinking and he doesn’t drink ALOT just enough that he feels good. He’s never been violent towards me or my kids, ever. He’s only been violent while on drugs, not drinking. The job my husband got him, the boss will be drug testing him monthly for 3 months until he’s sure he’s clean.

I know I have kids, they are not in danger and he’s never left alone with him ever.
