<human>: Give me the gist of the text in a nutshell

Background - My little brother is only 20 years old. He got married to this woman about a year ago. She has problems that she won't get help for. She gets mad over him visiting or parents because they used to be drug addicts (it should be noted this was when we were toddlers and since then have turned their lives around). He is not allowed to hang out with anyone without her. He has to clean the house everyday even though she never lifts a finger to help. He watches her children all day and then when she gets home tells them that "he isn't your father you don't have to listen to him." She has attempted to run him over with her car twice now. She kicks him out of the house at least once a month but he always goes back. 

The last time she kicked him out though, he came to live with me two states away. He has been here for about three days and the whole time she has been texted him telling him she has divorce papers and she can't wait to get out of their relationship. Today however it has hit her that she will never see him away and she loves him etc. so she has been texting him asking for him back. He ignored her until she started saying she can't take it anymore and she was going to kill herself. So of course he starts calling her and texting her. I convinced him to call the police and have them check on her for the kids sake, but there was no one at their home. And she keeps calling every 30 minutes and every time he gets more and more upset saying how he wants to go back and she needs him.

Bottom line is she's just playing him and wants his attention. It kills me to see my baby brother like this. What can I do to help him Reddit? What can I say to make him see the truth?
<bot>: My brother's crazy wife is threatening to kill herself and he wants to go back to her, two states away. I need help showing him why she is toxic.
