is this lust or love chemistry? Should i go and find this person?

[Smile4MeBaby]

In sophmore year i sat next to this guy in my biology class. He was a country boy; very funny and intelligent. We were assigned seats to sit together in the back of the room in a small crowed space. So often times our arms would brush together( he left hand/ im right hand). Sometimes our arms touches and it feel like an electrical shock up and down my body electrifying every nerve there is. He feels it too and we would joke about it, since i was a science class, we just though something in ther was electrically charged. And then it got to a point i started to like him. and i notice from him too. he would get a shy and blush all the time whner he saw me and sweat profusely. I did too but tried to hide it by smiling. it ws torture for us to see eachother. it never got nowhere, the school year ended and i left. i moved on dated and had been in a long term relationship. I never forget about this guy. Is this chemistry in body that send signal to certain people only? Why do we feel this way
why do we feel this way toward certain people only? Is this chemistry? Lust? It was more than that. it was like our mind can think together. we felt the same thing...we finished eachother sentence. and even though it was for a breif time in that one year. i can never find or feel that way again....
