Give me time and I don't know what I want?

My guy ended things with me. 15 minutes after he ended it he text me again saying that he doesn't know what he wants.
We continue to talk about us and our issues and he asked me to give him time.
He is going through something major.
He knows I am there for him and knew this before ending things so my role had nothing to do with why he ended it.
So what does I don't know what I want and give me time mean especially from a guys point of view?
