Oops, it's too long to quote. I think it's because if you are in her shoes, you probably kick that man already before seven years passed. It's a long time, seven years that won't ever return. I cheer for FL, she has her priority sorted. She's successful, rich, has a good social standing, is a good mother and is a tolerant and supportive wife. She has no flaws. They even sleep together regularly. When it's time to get divorce (I think she's ready to divorce anytime it becomes too much to handle or anytime he stop loving him, it's not like she never consider it), she could safeguard her assets as it's very clear that the husband does so many bad things from emotional and physical abuse to cheating and supporting a mistress openly. Well, there's a lot of dramas where FL has to be reborn to change her life after being a total fool who gets robbed of everything including the most extreme one is internal organ and life.
But really, we shouldn't take fiction seriously. You just need to find drama you like. Drop them if you dislike them. There's a lot more, never-ending drama supply waiting.
