I think JT is saying that eventhough she cheated, he loved her so much, he'd have the capability of forgiving her had she only told him and been honest. 'Honesty' plays a part in a lot of JT's songs. It's perhaps the most important quality in any relationship. It's a great message to us all that he is portraying; Love blinds you to many things, makes you vulnerable, leaves you weak. Be wary when you love. Always remain wary.
