Absolutely a difference. Your love for a parent or child or even a pet is everlasting and unwavering. It's there and never changes. It's quite common to "fall" in and out of love with an unrelated individual - that is subject to change.
Yes!! My friends and I hav a little system that pertainsto the opposite sex: First there like-when u like sum1 just friend level Then there is Love- feeling strongly, really caring abt them but doesn't mean u hav romantic feelings for them Then the normal like-being attracted to sum1 "like like" Then there's being "in like"- u really like them like bf gf just not LOVE, which is what most bf gf relationships r when ur not seriously dating And then being in love-truly loving someone
