A Free Relationship

Maisie Stone has known Ethan Ford for 15 years. She's gone from being a young woman to a married one. She's also gone from being Ethan's true love to an old flame.

He cheats on her repeatedly, and she forgives him every time. After a suicide attempt, Maisie finally sees the light.

This rotten world is just a competition to see who can be more shameless than others.

In an open relationship, both parties live their own lives. Since he's messing around with her sister, she can mess around with his friends and brothers.
