<human>: Hey Reddit, I'm going to be a junior in high school and my best and closest friend [M, 18] is leaving for college next month.

I can tell him anything, and we've gotten extremely close in the past year and a half. We have been FWB's for the past half year. Last year, I saw him almost every day, since we went to the same school. I'd see him in passing between classes, and we'd hang out occasionally during the weekend and have fun. We'd text almost every day. No relationship ever came of it, and we both didn't want that, either.

Recently, we got caught together when my parents snuck through my phone and read my messages, so we mutually agreed to stop texting each other.

I love him as a friend and companion, but I know I would never date him because of certain personality aspects. I don't know if I mean as much to him as he does to me, because he would never admit anything like that unless he was in a relationship. However, I do know that I matter to him, just maybe not as much as he does to me. That's okay.

But, he's going to college next month, and I won't see him anymore except for **maybe** during breaks. Since we won't talk or see each other much anymore, is there a realistic way to maintain our friendship? We agreed to keep some distance for now, but said that once school starts again we could just shoot the other a text or call and catch up a bit.

I know high school friendships rarely last through life, and I know we'll probably end up talking less and less until we're just strangers or acquaintances again. However, this makes me incredibly sad because I don't want to lose such a close friend. It feels like a friend "break-up" and I'm terrified of losing him; I always look back on people who used to be so close to me, and seeing how they mean nothing now hurts a lot.

Can you condense the text into three sentences or less?
<bot>: best friend [M] is leaving for college and we won't be able to talk much or see each other, can we still realistically stay close friends?
