Needing love advice

My ex-boyfriend went to jail a month ago & he hasn't called in 2 weeks almost. (Which is why I call him my ex) I recently exposed some shocking news to him. That I cheated on him in the beginning of our relationship. I've been lying saying I never cheated. He knew abt it but I just couldn't come clean. Now, that I've come clean he's mad at me. I just need to know what I should do to get him back. 😩😩😢 y'all I literally think abt him everyday and night. I miss him. He was my everything. I just don't know what to do. & before y'all judge me, we both were doing our dirt at first. After we got serious I quit being unfaithful. Which I cheated w. My baby daddy. ONCE & been faithful since. Nobody's perfect..right? 😭😭😭😪😔
