"'Till tonight I never knew the difference between comfort and love"
I think the guy realized he wasn't actually in love with her. He felt comfortable in a relationship with her, like that he could tell her things and wasn't afraid to be affectionate and all that. However, when they broke up, he realized he didn't actually love her...he just wasn't afraid to be with her. There is a difference between being comfortable with someone and being in love.
