<human>: Can you condense the text into a few key points?

My [20F] friend [21M] used to go to the same highschool as me until he moved away around our senior year. Since then we've talked a lot online but never anything too serious. Relationship things never come up, but we've become a lot more acquainted with each other and i feel like we've come a long way in terms of friendship. We have a lot in common and I always enjoy having conversations with him

I decided to come visit him across the country since I'm taking this summer off, but it turns out he's working a lot so I don't get much time with him during the week. We had a nice weekend when i first arrived, but during the week he's too caught up in work and some summer classes to give me much time. 

I'd like to think it's just because of the circumstances, but I feel really apprehensive about admitting my feelings for him. I'm pretty sure he feels uncomfortable around this kind of stuff and I'm afraid of my feelings not being reciprocated. Should I tell him this weekend when we have some work/school/stress-free time together? Is it crazy for me to develop feelings for him in this amount of time?
<bot>: Acquaintances in high school. He moved away. Talked a lot more online since then. Came to visit him across the country and don't know if I should confess feelings to him or not.
