I seriously cannot stop thinking about him!?

i met this guy about a few days ago at a party and we hit it off right away. we both really like eachother and hes really cute! and he told me i was beautiful, sweet, crazy (in a good way), and nice. i told him the same. we talk a lot and txt too. we are making plans to meet up for the week end. but the thing is he lives in the city and im really scared it will not work out. i live in the subarbs and about a half hour away from him. we both have the train and can get a ride down to eachothers houses. but im still very unsure. all i do is think about him and wish im with him. hes told me hes wanted to be with me a few times too. he was so sweet and asked me to dance with him at the party and sat down with me and he even fed me a bite of his doughnut. i thought he was being so nice and cute. he would hug me and rest his chin on top of my head while my head was on his chest, while we were slow dancing. and then when we were really dancing he was grinding with me and only wanted to dance with me and didnt leave me the whole night. and i just cant stop thinking about him! is this crazy? what do i do? what do i tell him? i really really like him...i almost think i love him..is that crazy?
