I'm just trying to figure out if I might let go of it by speaking to him. As it stands I pretty much hate him.
Regardless of whether you go or not, here is my advice:
You say you hate this person. For as long as you harbour any negative emotion against another person, be it hate, anger, fantasies of revenge or just irritation, you are giving THAT PERSON THE POWER OVER YOU.
Why? If you harbour these negative emotions against someone, they have the power to enter you mind, unannounced and at any time, spoil your day, ruin your mood and have long-lasting effects on your life and relationships.
