When your boyfriend needs a break.

My boyfriend says he to be alone to deal with his mental health. He says he doesn’t want to take a break or have space, he just needs to be alone. Then he says he wasn’t ready for a relationship, he’s just in a bad place rn and needs to figure it out. What should I do? I’m going crazy wondering what is going on. Should I just try to cut off communication with him until he is ready? What if I wait for him and he doesn’t come back? This is killing me.
