Not harsh. I would just say you reacted to whatever feeling or sensation he produces in you. That is the purest expression of how you feel towards him. And it's fine actually, you will eventually react differently. Oh, and to your question, no, it doesn't matter honestly.

Yeah maybe, you might of been a bit harsh. We don't always get to be friends with our ex's (some of us do and some others don't) it doesn't hurt to say hi.. At least something though, small talk thats it you don't have to tell him what his missing, but its understandable if he has hurt you in a way for you to become (sorry using this word) bitter to him
