as even broken hearts may have their doubts

You don't have to like something, you just have to learn to accept it. If it's not what you would do or it's not how you were brought up- I mean that's your opinion ; other people are gonna have theirs. Sometimes you have to put aside your opinion for something and see it from the different points. There's no need to make others miserable because you don't like something that they did. If it's what someone wants, learn to accept it- grow to like it, even. But don't not give something a chance.
