is this it?

well you can differentiate it by yourself. I mean, a person who is inlove can feel it. If you have a deeper feeling to that person and you wanted him always on your side, it can be love. You can do anything for the person whom you love. You can stop that feeling because whenever you tried to stop it, it grows and your feelings bout him also goes deeper and deeper until you found out that you are really fell inlove with him.

I think it depends upon the person. For me, it was always blushing around the person and what I can only describe as knowing it in my heart. I personally don't think that it's really something that you can prevent. Sure, you can deny it as much as you like, but then you'll never know if that person was really 'the one' or not.

I think its something you just know. It's when you actually can't imagine being without that person. It's wanting to be apart of their life for as long as possible. Of course, not many people can spot this feeling right away. It is not possible to just STOP it, but you can fall out of love.
