Britanica

It sounds like he is involved with a woman who had a sketchy past. She was either involved in sexual favors, was abused in some way, or on drugs. He reassures her that he wont tell anyone about her past and that she can have faith in him and his feelings. He is being true to her and wants her to know that she has nothing to worry about anymore, she is safe with him.

She is speaking on a close friend she had who was perfect for her. She loved him but never told him. She came to realize he felt the same way for her but it was already too late. Everyone was aware of what was going around them, but them. After they were living completely separate lives, they come to find out. Almost being in love just isn't enough.

She is depressed and lonely. She feels all alone and hurts herself over and over again. She has this thought of not being good enough in the back of her mind and it destroys her. The mistakes she keeps making eat her alive. She looks to the person and wants this them to just be there for her. Not asking any questions, allowing her to unload her heart onto them. She wants this person to breath life and hope back into her heart. To have faith in her.

It sounds like she made a mistake and corrected her ways for him. He forgave her for what she did because she couldn't be without him. It took her making a mistake to realize that. Now, that he made a mistake, she felt she couldn't handle it. She is confused, hurt, and lost. She is lost on the roads that once lead to him, so he has to use the "maps" that lead back to her. He wants to mend the relationship again.
