love is a deeper more affectionate longer lasting feeling someone has for family, friends pets, - even food, football...whatever
being in love is a passionate love, in which is mostly just one special person who makes your heart skip a beat or soar, when they walk in the room...you want to touch and look at them etc.
as much as i love my mum - my heart doesnt thud when i see her... cos im not in love with her...
(it would if i saw my grandad however...but only cos hed be a ghost..lol)
