My ex boyfriend wanted me back...

I'm 13 female and my boyfriend is 13 male. About a week ago my ex boyfriend asked for another shot. He told me he realized he fd up and that hes sorry. I told him yes of course. I love him still. It's was all fine until, Yesterday my boyfriend told me that he needs space to find himself. I told him I can do that. We haven't talked since, but before that he threatened to break up with me and told me we don't have common goals, or same beliefs. Which is weird because we have so much in common and me and him both know thst. When we first started talking he told me about him I told him about me and we were surprised by how much we had in common. I told him that if he think he will be happy without me he can do it but if he stays ill be so grateful and I promised to make sure I make him the happiest man on earth. I plan to keep that promise. I dont know where all of this came from me and him were fine before this we were laughing and saying we love each other all that cute stuff and now I just feel so sad without him. I hope he's okay. I do know that his cousin just died and they were really close. I hope he's okay. I miss my love and im not sure if he misses me too. I hope he does. I love him I don't want to be without him giving him space is really hard. I dont know what to do. Another boy is trying to get me to cheat on him and of course I ssy no but it just makes me wonder if he thinks he can go with other girls. I dont know im just so afraid.
