My brother is choosing to stay with his wife

Nobody in the family has ever liked my brother's wife. She's entitled and bratty. The first time we ever met her she made fun of our mom's speech impediment which my brother did yell at her for. She also has no issue emasculating my brother in front of everyone but talking about his him ejaculating too fast like we want to hear that shit. And just talks down to him in general. So this bitch is gun crazy. Has several. My brother has gun trauma so he doesn't like guns. He ended up in the hospital last month for a gun shop wound in the shoulder. He said he was cleaning the gun and accidentally shot himself. Yeah who's buying that? He did admit after he got out the hospital to me his WIFE shot him because they had a fight and he said he wanted a divorce. He was gonna leave her and everything, he said he just needed time. Now he's saying they're gonna work it out. Which I called him stupid for. She SHOT him! There's no coming back from that. I asked would she at least be getting rid of her guns because IDC what anyone's opinions on guns are. Once you have proven you're an irresponsible gun owner, you don't need a gun. He said he would talk to her about it and he did and she said no and I'm like.... He's seriously okay with staying with a women who SHOT him and let her keep her guns? This is stupid! Beyond stupid!
