Old friend... please read this if you have the time. I need some opinions

So I have this friend and I’ve known him for as long as I can remember. He’s the brother to my best friend. We all used to hangout at my house everyday and all day. I’ve always thought of him as a brother. He ended up moving away for reasons that I will not say. He rarely reaches out to me and if he does we only end up talking for about 5 minutes before he leaves me on opened. We have always been super close. To the point of talking about things I’ve never been comfortable talking about with anyone else including my beat friend. Well after he moved it all changed. He doesn’t seem to care anymore. And I get super anxious about this stuff so when I try to say hi and he leaves me on opened I take that as he doesn’t want to talk to me. So I’ve also stopped reaching out. I saw him recently for the first time in about 6 months. He didn’t seem as excited to see me as he used to. He also judged who I hangout with and everything about me. I’m angry at him because every time he’s been in town he never told me he never even tried to say hi. I really don’t know how to feel. It’s as if seeing him just upset me. I feel sad. I can’t stop crying and I don’t understand why. I missed him so much. I can’t even explain how much. So why do I feel so sad after seeing him... to whoever actually read all of this thank you. I needed to get things off my chest. And I can’t think of anyone of my friends that I’d want to talk to about this. I just feel like a burden when I talk about this stuff.
