Should I apologize or leave things unsaid?

Anonymous
My ex and I broke up a few months ago and we decided to not have any contact. Recently that changed for various reasons and we got back in contact. It didn't end well. During our last conversation I said some things that I shouldn't have said. Its been about a month since then and I feel as though I should apologize. I felt like I should've immediately after we fought but he was angry and I didn't want to make it any worse for us. Is it better to apologize so that my ex knows that I don't think those things of him or should I leave things be? He is the one that ended contact and I don't want to keep dragging along our past. Neither of us cheated or did anything along those lines, we just weren't ready to be in a relationship and it didn't work out.

Would you want your ex to apologize or would you prefer they just walked out of your life completely?
