Well, personally, this reminds me of a situation I'm currently in.
Basically, it's about someone that is falling in love with someone else, but they're really confused about it, because it's never happened before. The line "Just when I think I'm invincible, you come and happen to me." Describes the person's feelings about how their life was before they met someone else that was worth living your life for. That was kind of confusing. Let me explain. Basically, the singer thought they had everything figured out, and they were living life for them, feeling untouchable, when all of a sudden, they meet this amazing person, and they fall for them. Suddenly they realize that it's possible to live life for someone else, to share it with someone else. That's something that makes you feel very vulnerable.
