what do you think is the difference between friendship and love?

Love is sth u have for someone u wanna be together with , maybe for a lifetime. u'll always get sad on the idea of being only friends with him or her.u want more than that when u r in love with a person. And love is exlusive. u'll never wanna share with a third person.
Friendship is much less complicated that love 'cause u can have more than one friend but u can only have one lover. Friendship can also be profound but in a very different way from love does. In a friendship, u don't have to think about the future or sth like that. Everything is just so simple.

If you can leave someone for a long time without any heartache, you are just friends.
