Not a hard concept to understand or do! If someone wasnt faithful with you, they didn't love you. They didn't care about breaking your heart. When you truly love someone, being faithful & trusting someone is the most natural thing.
I grew up on Disney movies. Princesses and dragons and the prince that always saves them.When I was little I thought Cinderella really did live in the castle at Disney World. Hopelessly I believe everyone can still have their own fairytale.
