I’ve dated this guy for about 8 months. We were long-distance and I had a very stressful project at work so it took me a while to figure out I didn't want a future with him. I ended the relationship a little over a month ago and felt truly relieved after so I knew it was the right thing to do. I was very clear when I broke up with him. I told him I realized we were too different and I didn't see a future with him. He tried to call me yesterday and I don't want to call back. I cannot explain my feelings, but I feel a deep disgust towards him. Which I know isn't fair, but I just feel that way. It’s this “I really can't believe my hormones clouded my judgment so badly” feeling. A lot of his behaviors and habits just made me stop liking him as a person, not just romantically. And now that we're over I have zero interest in talking to him again.

Would I be that asshole if I just texted him and asked why he called?
