Mixed signals

I met a boy 7 years ago he was a family friend of ours. Ever since then he would come to my home town and visit for a week every summer (he lives 4 hours away). After each week we’d go our separate ways and only speak occasionally throughout the rest of the year. But when the next summer rolled around it seemed like yesterday I had just saw him no awkwardness just genuinely a special relationship. We both liked each other and later on we admitted that. Now im a senior in high school and he’s a sophomore in college. I made an extra visit during the summer to see him and we hit it off and I got to really connect with him emotionally and intimately. Since then (this past august) we have been talking every day, sorta like a long distance relationship but we came to reality about a month ago that we live 4 hours away and live separate lives and we don’t want to do long distance anymore because its horrible. We both agreed that if I lived up there it would be different. We also talked about my future college plans and we both planned on me going to college in the fall in his city so we could be together. But I just recently found out he has a gf. Im not upset about this because he is moving forward with his life and doing his thing and so am I, i’m just upset that I found out over social media instead of him. Our communication is not that strong anymore since we both have school and work so that could be a factor. After confronting him about not telling me he said he didn’t know how to tell me. Im kind of hurt since he tells me im his bestfriend and i’ll always be more important to him than any gf but that’s not a secret you keep from a bestfriend? especially one that likes you, but maybe he didn’t want to hurt my feelings? What should I do? Go to the college and risk not being with him (I do actually want to go to this college but there’s also colleges in my home town) or do I just go with the flow as friends even if he’s not single because our relationship is so special I feel like he would want to be with me instead? Best friends always end up together right?
