EX friends husband cheated with my brother

Wayyy back in July I made a post about finding out my friend's husband was having an affair with my brother. A lot of people got on to me for being friends with her because she used gay slurs towards my brother. Got with her husband when he was 16 and she was 27 and forced him to drop out of school. He did get his GED. She abused him and drugged me at one point to get me to cheat on my boyfriend. I realize now I was trauma bonded to her.... My parents were abusive and I raised my brother since I was 15 and he was 5. You guys were right. I went from one abusive situation to another and am finally her done. Her husband had had enough too. I found out about him and my brother (they're 19 and 20) because he's in the military and lives on base. He decided to live on base because she kept putting her hands on him. I found their letters between each other and they were raunchy and sexual.. This relationship had been going on quite a while.... She came to me upset one day because she got a letter from him and they were divorce papers. She freaked. I ended my friendship with her after she pushed me over a balcony because she got violent drunk. It wasn't just that... It was everything and realizing in therapy I was in a trauma bond. I did have a conversation with my brother and he said they first slept together the night her husband came to see her and she got drunk and choked him. He went to see my brother because they were close friends in high school. He cried. They got drunk together .... And fucked ... Then kind of fell for each other... So he was divorcing her to be with my brother completely. Well she found out about the affair and all hell break lose. He came to me for advice because he used to do that since I was pretty much my brothers parent... And I was there for him. She then tried to say she would report him and get him dishonorably discharged for adultery unless he paid her.... So he was going to.... Then he decided instead.... To turn himself in and tell the truth. He went before court last week and ig said everything about their relationship. His age. The abuse. Everything. I was expecting him to be dishonorably discharged.... But he was cleared of all charges. Ig everything happens for a reason. He recently asked my brother to marry him and the most exciting thing I have going on his therapy. I guess I just wanted to update you guys on that situation and you were right about her. I spent my whole life being abused so I let a friend do it to me.... I finally let go. And ig my brother got his happy ending.

@Jade thank you! I'm hoping in therapy I'll get into why I continue to form these trauma bonds and be able to have healthy relationships and friendships. But now I'm able to recognize red flags better.
