.....I've definately fallen in love several times (romantic love). It's a suffusion of feeling, like ink in water as the other person gets inculcated into my life and heart. At first it's very concentrated and localized emotion of warmth, excitement and anticipation. For me it's rather like a thrall of hope.

It diffuses over time, equillibrates and becomes very comfortable and safe. Even when (or if) it doesn't work out, I'm forever tinged (usually in a good way) by my experience with that person.....
