Break up advice?

My boyfriend decided he didn’t want a relationship after 3 years right before our 4th anniversary. His explanation was that he wanted to better himself before he can be in a full relationship. I understood him and we settled as being friends. I love him to death and he says he loves me as well and when the time is right we will make things better. We’ve gone out since then as friends but he makes a move. Or we get really close and comfortable again which has been really confusing me on what he wants from me. I confronted him again on what it is we have going on and he still says he doesn’t want a relationship. It’s eating at me. I am uneasy everyday bc I know I was the best possible version of myself through our relationship. I need some clear advice 😔
