I agree with some points of saulhudson90 but not all of it. Its about 2 people that were together before. Girl left, now with another man, but she is suffering. From the lines.
Frozen with fear - girl is scared in the relationship.
All out of love but I take it from the past - man is no longer in love but for the sake of their relationship before, he will console her.
All out of words cause I'm sure it'll never last - literal meaning, he needs to take action.
I can't save you if you don't let me - girl doesn't want him to be involved with her problems.
You just get me like I've never been gotten before - this is the most striking line of the song, where the girl really knows what the man wants to help her despite of their separation.
