o found a truly depressing ending - she kills Chris, but Hutch takes it upon himself to go to jail.
I will also say that after the second installment it's hard to even think about a positive ending to the story. Someone has to take the punishment for this and that punishment will take a hard toll on all the characters in this novel.
I don't see many good endings at this moment, maybe:
1. Chris at some point truly fell in love with her, some turn of events or simple change of heart/some life-changing moment.
2. Hutch/Chris/Vivian ends in poly relationship
3. They somehow survive all this drama, still together, but never the same again - it will leave scar in them/their mental health
and something bad:
1. She become Chris slave + brainwashed completely
2. Happy Hutch with x girl. Where Vivian ends in mental institution. Her current condition is even worse than before, and story will go only darker
3. on the street, cheap slut selling herself for a few bucks

Happy Hutch at some point meet her with his new gf and throw her few bucks, out of pity

4. Vivian suicide, or Hutch has enough and kill her/ or both
5. Hutch "The Last Resort" killing Chris and free her from him
6. Hutch suicide, as I said before, he's walking depression now
