Should I take my ex back?

There was no cheating or abuse. He broke up with me because he was unhappy with relationship. Recently he told me it was because he felt like he wasn’t making me happy. I told him it was because he wasn’t even communicating this or any else of his frustrations. He told me he would change this and that he made a big mistake. I am thinking of taking things slow or possibly dating him and other guys at the same time. I don't know, he really hurt me.
