I am chronically ill, and have gotten progressively worse as I've gotten older, despite doing anything I can to get better.I was previously in a very bad living situation that was impacting my health to the point that my skin was tearing open. Because of this, someone I thought cared for me offered to let me stay with them indefinitely. They said they would help me get better.This person is polyamorous, and so is their husband. This person has a current partner who the husband is also involved with. And then, slowly but surely and not even a little bit intentionally, he and I fell in love.This person said that was totally reasonable. They said they were fine with it. I tried my best to maintain an open dialogue. I never even kissed him in front of them, and kissing is as far as we went. I would even ask them before holding his hand.Apparently, they realized that him being in love with me and me loving him was something they did not want. Even though they're in love with their other partner.Upon this realization, all aiding me in my physical health has ceased. The decision has been made to send me back to the house that nearly killed me. I have been locked in my bedroom as I wait for that day to come. It has been six days. I am allowed out to use the restroom and bathe. I am told I can come out more often, but it has consistently resulted in this person having a breakdown and threatening to leave their husband and hurt themselves.I have had one meal in the last six days. This person's other partner has been getting me water. Their husband works long hours, so I don't think he is aware of the gravity of the situation. He has only agreed to this so they don't leave him. The problem, is that there is still a very good chance that they will still leave him, because they cannot handle that he fell in love with someone else.I know he doesn't want them to leave. They are extremely emotionally and verbally abusive, though, and have dangerously destructive tendencies, along with a dishonest streak. They say horrifically cruel things to him, and sometimes to their children, too. I would like help altering their algorithms on their social media to show content that makes them unable to get over their husband loving someone else. Whether it be content claiming that "cheaters" never change (they say he cheated, but insist that they haven't, despite doing far more physically), that "if you are in love with someone and fall in love with someone else, then you never really loved the first person," and various similar concepts.Also, anything else that you could think of that would make them leave.I appreciate anyone who took the time to read this.
