That's what this book was. It had a good starting idea, the main characters when friends since they were kids, and Amy didn't love Logan since always, she develops feelings for him.
It was all pretty nice until they have sex, and then go on a sort of date, and Anna Romo, the lost sister, decides that, even when Logan says to her that he's there with Amy, she gets the idea that she can "change" his mind and kisses him, because "no men has told me ever no"...
Bitch. Since when you kiss a guy when he tells you he's on a date with another woman? And then when he's like "Stop" you still try to kiss him? Wow, Calm yourself and go searching for greener pastures.
And then Logan is not exactly decided, and it makes the whole thing "meh", I just lost interest.
