I think it's about a guy looking back on his relationship; he had good times and bad times and sometimes he wasn't sure how he felt towards her.
he felt very attracted to her, and she liked him too, but she still felt that she needed to be rid of him for some reason...
"and fear made you so unsure of me"
maybe she felt he had a bad influence on her, or perhaps she thought he was cheating on her, but he isn't like that at all, so that's why he sings "seems like you never really knew me"
