I didn't think this was possible until it happened. How can this be explained?

If you feel sparks for somebody right away, don't ignore it cause it could be love. I had the weirdest feeling when I met my first love, like he was going to be in my life a lot, and he was for the next 6 years, and I'm still in love with him. I don't know if he feels it for me, but I know he cares about me, and we'll always have that bond.
