He wants time to be single

How long will it take? I didn’t do anything wrong and he made that clear, he still cares about me and there’s no one else, but he wants to be single. I love him and I don’t want to move on. I know if I really try, I can, but I do not want to and after over a year it’s so hard. He’s the best thing that ever happened to me and somehow he got away. Wrong timing I guess, never been so heartbroken. What do I do? How long do I wait to talk to him? To at least be friends? I just want him back but I’m not going to pressure him, I just want him in my life.
