Please someone help me

Me and my ex were together for a year and a half since September 4, 2023 He broke up with me eight days ago on Monday at 3 AM because I wanted to talk to him about how I feel being depressed and having crazy thoughts. I wanted his help and I needed his love and affection, but right then in there, he suggested that we should break up and remain friends. I don’t know what to do because we’ve been remaining friends since because I keep getting memories at school of us being once in love. I want him to come back, but I don’t know how to convince him because he thinks it’s his fault but I feel like he’s gonna come back soon. I just don’t know when but I really love him and I can’t do this by myself.
