Sometimes, the people that tend to hurt us more are those who we've already told our deepest secrets. They know what has hurt us in the past but still use it against us later, becoming just like the rest.
Some people are fond of using one's past against them when in an argument. They feel it's the easiest weapon to use. Don't ever hurt someone this way by bringing up their past, it's not a weapon you should use against them. They opened up to you because they trusted you, so keep that secret even when there's an argument between you two.
