Lyric discussion by stereofidelic 

She never expected her lover to treat her so well, "ive been swallowed by your kindness, every part of me is breaking down" But to the point where shes almost paralyzed with strong emotions for him. She keeps a shield up, but he found a way past it "my disguise you saw behind this, you pushed on and set me free".

I'm getting deep here, but i think its saying that no one likes to be caught off guard and taken for a fool or fallen in love too quickly... but in this song she's saying "And it was in protection, You held on with such certainty" meaning that he is actually a good person and she can trust him.
