When one comes to know that he is fallen in LOVE ?

When you always think of her every hour every minute. You want to be with her forever.

When you always think about a person in every second and feel to talk and stay with them.

The two previous posters have said what need be said. She is always on your mind. Her presence makes you energetic and her absence puts your heart on fire. If she doesn't speak to you even once you are restless.All this happens if she is in your vicinity and you have fallen n love with someone you can keep seeing. I have no experience of long distance relationship.

When you sleep at night, what do you dream about? Do you dream about your girlfriend? When the phone rings and you think it's your girlfriend, what do you do? Do you jump up immedietly or do you just sit there? Do you have butterflys and feel that "funny" feeling when you talk to her? Would you do anything in the world for her without hestitation? Is she all you think about? When another girl passes you by do you look at them? If not, then that means you are fully devoted to her. Most of all, would you marry her and give her your whole life and full attention? Then you love her. :-) Good luck in your journey. ~Melanie
