Does he still like me? I think hes my one..

hey guys! this is a suuuuper long story but i have no one else to talk about it with and im looking for some advice. i really need it.

it all started a few years ago, me and a guy in my class were flirting a lot. he eventually got a job where i work and thats when i really started liking him. we had a very intense touchy feely flirting going on, and my heart would beat so much faster whenever he was around. i hadnt felt like that about a guy ever in my life.
it gets a little complicated because i started to talk and hang out with his sister a lot, theyre twins.
one night me his sister and him were hanging out at their house drinking, and me and him ended up hooking up.
after the first time we did it a lot, (never having sex, just fooling around) and i really liked him.
we would hang out in groups with people and just stare at eachother, like we could read eachothers minds or something.
i could tell he liked me back, i have no doubts about that, but his sister ended up finding out we would sneak around and she got really mad.
so since we both felt bad we decided it would be better to stop fooling around. we would still flirt all the time, and every once and a while we couldnt help ourselves and we would hook up.

a few months passed and we drifted apart and he got a girlfriend. but we still worked together.
after dating this girl for a couple months he started to flirt with me a lot again.
they eventually broke up, and we all moved our seperate way to go to college.
i havent talked to him much, just seen him at parties but i still feel these strong feelings about him, and i get too nervous to talk to him.

i want to know if i really am in love with him. i just cant stop dreaming about him or get him off my mind. anyone have anything similar happen to them?

its summer now so im gonna be seeing him around town and at parties and stuff so i dont know what to do.

You are not in love. You have the excitement of "new relationship energy", it happens all the time. People mistake NRE for being in love. It's not the same. Love can only be built after a while of being physically together, it takes time to grow.

Also, why do people say "hooking up" when no sex is involved? Does this refer just to "making out"?

And why are you letting his sister control your life? Why aren't you just dating this guy? Who controls your life? You or the sister?
