PLEASE HELP IDK WHAT TO DO

Hi, I need help please, I was in a long distance relationship for 3 years, during those 3 years we only broke up once, and after that we fell so hard in love we were freaking best friends we shared so much!!! It was like we were freaking soulmates!!!! then last year around October he told me he didn’t feel the same way anymore, i was broken and told him i needed time i told him to give me a month, but after 3 weeks he contacted me and told me he missed me, i fell for it and broke the 30 day no contact, we talked again all normal but he started detaching himself again, then on December 25th he told me he was seeing someone else and that it was getting serious (he told me this through FaceTime) when he said that all i told him was “have a good life” and i hanged up on him i didnt let him say more then, hours later i sent him a “goodbye” text and he never replied to it and it seems hes dating this girl already, i miss him so much i havent contacted him at all! It’s gonna be a month without talking to each other this Saturday the 25th….i want to talk to him and earn him back go back to how we were, i still havent accepted hes moved on! So i have been doing this 30 day no contact rule again, but im worried he’s not going to reach out this time💔 today i saw he unfollowed me from instagram after literally watching my stories none stop but he still follows my finsta what do you guys think??
