I've never been in a serious relationship where a girl had been in love with me (I'm only 16:p) so I can't really say how much I'd appreciate being loved in that way. But if a member of my family was to say that they love me it'd probably mean very little as it's really a given. I'd expect members of my family to love me because that's what they do. It doesn't mean that they like me, they just get attached to me in that way because they've been stuck with me for 16 years. If anything It'd mean far more to me if someone told me that they liked me as a person.
