If you love someone, coz you think he/she is really gorgeous, then it’s not love, its infatuation.
If you love someone coz you think you shouldn’t leave him/her , it’s not love : it’s compromise.
If you love someone coz you share everything with him/her, then it’s not love it’s friendship.
But if you feel the pain of other person more than your’s, even when he/she is stable and you cry it’s love.
If you get attached to other person but stay with him/her without any regrets then it’s love.
If you let him/her go knowing that he/she has to go even though he/she doesn’t want to, then it’s love.
