<human>: Give me the gist of the text in a nutshell

I'm sorry for any formatting and sorry if this isn't the right place to post. 

I started college last year in the fall and a school very far away from my hometown. My high school friends go to college relatively near our hometown. During highschool my free time was predominately spent with them.

Now that I'm much farther away, my friends and I (obviously) don't see each other or hang out. You gotta do what you gotta do right?

But I'm starting to think that the effort I'm putting in to stay friends isn't really reciprocated. I'll initiate conversation about how their school is going but I won't get a response for a couple of days.

Right, everyone gets busy and I understand that and I hope I'm not coming off the wrong way. It's just that none of my highschool friends every showed the initiative and initiated a convo with me first.

The two people mentioned in the title are my closest friends(A and B). One of the other friends in the group, C, went up to A and B's school for the weekend. Obviously with the young adults in today's society people document things on snapchat and seeing them hang out makes me sad. I'll see the snapchat stories and just try to surpress what I'm feeling but I don't know I just feel really shitty. 

Like B messed up summer plans because C visited and forgot that I messaged him. A probably noticed that I've been seeing the snapchat stories instantly and probably just wanted to go through  the motions, messaged me like 3 in the morning, probably because b noticed I was disappointed that summer plans fell through.

I feel like friends should be a two way street? Is it wrong to expect that they would care about how I doing for the past 2 months of college? After I try to start convos at least once every 2-3 weeks? 

I'm making more and more friends at college. Is it time to accept that there's a chance that my high school friendships won't be that strong or even existent in a couple of years?
<bot>: friends from hs do not seem to replicate the actions of staying friends and keeping up with each other and I wonder if it's time to just let it go
