Will leaving make him fight for me and come back?

My boyfriend ended the relationship saying he doesn’t know if we have a future together and that he is lost and doesn’t know what he wants for his life ( he is 40 years old), and we work together but he acts like he wants to comeback but he doesn’t. I talked to him many times, he say he loves me but he is not ready to comeback yet, but at work he acts in a way someone who wants breakup wouldn't. I thought that he is taking me for granted because he knows I really love him and he knows Im working there and he doesn’t think I will leave, and he doesn't want me to leave. Do you think If I actually give notice he will wake up and comeback? I work at his restaurant and directly with him. He still has our pictures on his fridge door, he say he is stuck on me and that he is not ready to lose me but he doesn’t come back... I need Help
