Scorpio man & Aries female. Disrespect?

I wouldn't have thrown a fuss over something minor, like dinner. But as said, this was an important promise. I ended up taking myself there after leaving his place last night, and he sent me a text about an hour ago asking if I went and did what I needed to do last night. As of now, I can't even bring myself to feel anything other than slight annoyance, but more nonchalant than anything. A part of me wants to be pissed and call him every name in the book, and a part of me wants him to know once again how pathetic his actions were and how he hurt me. But I'm completely nonchalant. I can't even bring myself to throw out the energy to tell him anything, because I know it wouldn't matter in the end anyways.
Nearly 28 years old and has even been married in the past. You would think he would know how to be somewhat of a man.
