Breakup.

Does your ex really come back? We broke up a few days ago and our breakup was his decision, and I dont know if it was out of anger but he kept telling me he needs space, but he told me we were 100% done.. & when I asked him awhile after that if we would ever get back together he said idk.. I mentioned to him how Id let him come around to me and that was the last I messaged him and he just ignored majority of my previous questions

Do you think he will come back?

How long should I wait before saying "he doesnt want you, move on"?
