How do you tell if you are obsessed with someone?

Well, it sometimes can be called as the same thing, but I would say if you are obsessed with something you feel strongly that you need/must do it. Answer If you really love someone it is more of an unselfish feeling. You will love that person for who they are, you will want what is best for him or her, and will put that person before yourself - you will want to do things to make him or her happy. If it's obsession, it will be more of a selfish feeling, you want what's going to make yourself happy no matter how the other person feels, your own needs are uppermost in your mind instead of the other's persons needs and wants.
