Is OTHER wrong in the post ? POST : My younger brother is almost 28 years old, we'll call him LB for Little Brother. He's currently going through a divorce with his manipulative and emotionally abusive wife. She's blackmailing him into giving her more child support than he should, and manipulating their custody agreement. It's a mess.

He's been living with our mom and step dad for the last 6 months while he's dealing with all of this. My step dad is a good person, with good intentions, but he doesn't have any kids of his own and has a hard time dealing with them sometimes. He also has some anger management issues (not abusive or anything, just gets irrationally upset about things). LB is wearing out his welcome there, and it's getting hard having his 3 year old there when my step dad doesn't always do well with kids.

&amp;#x200B;

Because of the child support blackmail, and the fact that he's notoriously horrible with his money and spends way too much of it on weed, he's having a hard time finding an apartment he can afford.

I just just moved into a new apartment. Two bed, two bath, almost 1k sq ft, affordable. It's a great little place, especially in the kinda shitty housing market in Utah right now. I'm going through some relationship issues of my own, and my SO may or may not move in with me, depending on how things play out.

&amp;#x200B;

My mom told me that LB said "if SO doesn't move in, maybe I'll see if she will let me move in. There's plenty of space." He's not wrong about that, but I don't want to live with him. He's a serious fucking slob, I like my house clean. He's terrible with money, I don't want to have to cover for him.  I can afford this place on my own. I like living alone.

&amp;#x200B;

I know he's in a terrible situation, but I've spent the last 6 months working on my mental health and establishing boundaries with people, my family in particular. I feel like a bit of an ass hole for not wanting him to live here, but I feel like it would counteract everything I've been doing to get my own self to a better place, mentally.

&amp;#x200B;

So, am I the asshole?

&amp;#x200B;

TLDR; my 28 y/o brother is going through a messy divorce and has overstayed his welcome with our parents. I just got a new place with an extra room, but he's messy and terrible with his money and I don't want him to live with me. AITA?
