Helpless

Maria Reynolds is in an abusive relationship with her husband James. He beats her, cheats on her, and now, is making her make Alexander Hamilton cheat on his wife, Eliza.
After a month of clandestine meetings, Eliza walks in on the two in her and Alex's bedroom. Instead of being obviously mad (even though she was pissed inside), she asked them why. That's when Maria told the two of them everything. Eliza sympathised with the other woman and the two became quick friends, and after a few months, they both developed feelings for each other.
Alexander was kicked out of the bedroom, though, because he still cheated, but then John Laurens, Alex's "best friend" moved into their house once his own house burnt down, with his wife inside.
Now there are four people living inside their house, with Maria and John in a "relationship" and Alexander and John in a "relationship" as well, since it was a homophobic time and they'd get publicly shamed.

(Yes John Laurens is alive in this timeline, he never got shot)

The characters aren't mine, they're historical figures but look like how their actors looked in the Hamilton musical.
