Need as much advice as possible!!!

I know I’ve asked this question many times on here, but I need more advice. My guy best friend and I had sex twice one weekend he was back home. After that, we called every night, got intimate over the phone, talked about me flying to him, and told his fam and friends about me. One day, he told me he just thinks we should be friends bc he isn’t ready for a committed relationship, let alone an LDR. He said it was just bad timing. I believed him but it hurt so bad. For weeks I overthought so much and kept being stupid and asking him for reassurance on us staying friends. Every single time he’d reassure me we would. Since we’re going back to how it was, I’d send him funny memes here every other day and some snaps maybe like once every 2-3 weeks. With the memes, he’ll like some and has even commented. Sometimes he doesn’t.

Last night I hung out with our friends and told them what happened. His ex roommate told me that he’s liked me this whole time (5 years). Whenever he comes home, he’ll always invite all of us to hang. I told them how worried I was that he won’t do that anymore but they all disagreed. They all told me that he will invite me to hang because he’s not the type of person to not do that. His ex roommate told me that this was prob a good thing bc LDRs are hard. He told me to let him do his little thing now and he’s sure things will happen in the future. Also, 2 weeks after we stopped talking I saw him liking pics of another girl and commenting on insta. He still is and my ex roommate told me it’s prob one of his little “tinder talks” bc he’s bored in the military. Even with all this reassurance, I still overthink and idk why. I sent him another snap tonight but he didn’t reply. Idk what to think of what to do. Out of all my friends, I’ve always been the one who’s talked to him the most and I’m trying to go back to normal but I’m confused. My friends barely talk to him and he’ll still invite them over to hang so idk if I’m just worrying and stressing about nothing at this point! Help!!!!
