This song seems to be more about an independent person who tends to fall in love on their own terms. Until they meet that one person that they start to have feelings for without planning on it (hence, "I feel a weakness coming on"). They are completely taken back by this, and start to try and fight back their feelings, but they can't. They feel a minor bit of resentment towards this person they find themselves involuntarilly loving (it's all your fault). And they find they have no choice but to just go with it.
