It's clear what the lyrics mean. The guy wants to get more serious because he's in love with the girl. The girl has a fear of falling in love. Although they are clearly sleeping together and in a relationship, the girl is very guarded and bottles up her feelings. The guy, on the other hand, is putting it all out there, but when he threatens to leave she wants him to stay. No, you do not have to be in love to be in a relationship or sleeping together. Describes my boyfriend and I perfectly.
