Can someone explain to me what this means?

You may feel like looking the other way when a friend does something you'd consider a betrayal, but that would not be in your best interest. If a person you trust does something to erode your sense of faith in the relationship, you owe it to yourself to explore further. Although you may find that there is a reason to be alarmed, it's more likely that this is all a misunderstanding. If you can approach the other party in a non-confrontational way, you can get to the bottom of things very quickly. If you don't, you concern may eventually cause unwarranted problems in the relationship.
