when can you say that you are in love?

Not until you really KNOW the person. Love is not instant. Love does not come quickly. Love needs to develop and grow before it comes into bloom. Attraction can be instant, but attraction can fade and die. The important elements leading to love are genuinely LIKING the person and sharing a mutual RESPECT. Possibly respect is the most important ingredient, because when there is no respect, there cannot be love. Love comes when two people merge their interests and their personalities, getting to know each other, respect each other and defer to each other. Genuine, lifetime-lasting love will only come when given time to develop.

when u dream and think only of one person....u suddenly like everything in him/her.

First of all one cannot know true love if they don't know God ... because love comes from the Father. Next, I think that too many people think that they are in love with someone when really they are only in lust. You will know you are in love when you are willing to sacrifice everything for the other person. When you are willing to put their needs first and deisre what is best for them before what is best for you. This is how I love my wife and how she loves me.

i think when you always thinking about that person then it shows that you have fallen in love with him/her...

You're in love... when you are always happy no matter what bad happened, when you always daydreaming, when someone shouted at you and you said thank you with a smile, when you always want to see the same person, you always want to be with him, you always want to talk to him, etc... Well i must say it's nice to be in love. :-)

when i think of nothing but him...every little thing he does sneds shivers to my spine..and if i have already sacrificed a lot.
