What do i do

He broke up with me bc his mom didnt like me bc she cought us sneaking out tg and she wanted us to break up and he did after a week or two of not listening to her and he told me after highschools over he would come back and he would be waiting for me and i said ok and he told me he loved me. Two days later i get a notification (im logged into his insta) and hes texting this girl saying hey ma you mad pretty and I confronted him but he blocked me and took me off his account and everyibe but his bsf blocked me so i texted his bsf and my ex went on his bsfs phone and started saying “you dont control me” when all i was doing is asking whats going on which is crazy because either waited for him and i told him id wait for him however long it takes but he coupdnt even wait more then 2 days he also doesnt have his phone so he uses his friends phone so i send him tiktoks and other stuff on snapchat but what should i do?
