If you still want him back, maybe you guys should meet up and have a talk. And if he goes berserk again, tell him to calm down and all you want is to work things out and it’s not right to just leave things like that. From what I see, (just my opinion) you both are emotionally attached but at the same time, wanting to move on (both of you kissed others). Your girl friends are right, he’s not worth it. He wanted a break up right? Sure, you are entitled to have fun and meet new people! He will eventually come looking for you again, but you really need to teach him a lesson 😎
