Moving on and getting over him?

Issy

My (ex) boyfriend of two years was my life. He talked me out of suicide, convinced me to tell my parents about my self harm and helped me seek therapy. He's been my only friend and I tell him everything. Not only that but he and I lost our virginity together. It's been about 3 months since we broke up. We broke up on good terms, he wasn't ready for a serious relationship and the titles and commitment scared him. Because of this reason we continued to see each other casually and intimately. We loved each other it was just the wrong time to be dating. Last week, he told me we 'should end it' totally out of no where. Today he told me he's talking to someone else. We aren't together so I can't be mad but I also love him so can't remain best friends rn. I need help moving on and letting go of those feelings so I can have my friend back. I don't want to love him, but I do. How do you stop loving someone so I can eventually have him in my life as a friend ??
