I ended it for him, how do I reverse it?

We were having issues because he is really depressed and I believe thought of us as a safety blanket. But I broke up with him weeks ago so he had time to work on himself, not because I didn’t want to be together. I feel I made a mistake and tried to explain I can help him through it if he committed to going through it with me. But we aren’t speaking now. I should probably just give him space until, if ever, he reaches back out. Anyone had luck in this situation?
