Like is... Exactly what it sounds like, having a likng for a person and thinking of them in a positive, possibly romantic way, it can often lead to love, but even more often gets mistaken for love, and that so often leads to pain and heartbreak.

Love is... Alot harder to explain, all I have to reference it by is my personal experience, but in my experience, it means caring about that person
more than or equaly to how much you care for your own life and well being, feeling sad and semi-heartbroken just being apart from them, actualy having deep feelings towards them despite logical explanation or all your sensibiliies, rather than just the logical thought involved in 'likeing' someone.

Really, the dividing line between like and love, is that like can be a logical thing, love on the other hand, follows no reason or rules, love is unconditional, like is'nt.
