At my former position, which was a warehouse position with supported employment, there was woman who's sister had guardianship over her along with living in a group home who happened to date another co-worker off an off who was also in the program but was more independent. They were together long enough that she wanted to cohabit with and marry him.
When she brought up marriage and living independently, they labeled her as "Delusional" and talked behind her back.
He dumped her and hurt her really bad though she was manipulative. I felt like she was not even allowed to have feelings and they stuck her in the same room with him and expected she would just let it go and move on with her life. Rather she displayed a love-hate feeling towards him. Rather than help her, they took his side and did everything they could to protect him because "She was a monster with some kind of mental illness." They were very cold and misunderstanding of her.
