I need relationship advise

Back toward the end 2014 in December, I had gotten in a relationship. He was so kind and send random paragraphs to me just out of the blue. We ended up breaking up in February with me since u was to shy to talk to him in person. I was reading old messages and I treated him like shit.. We're back into each other's lives and I'm more comfortable. I still have mad feelings for him. Should I tell him how I feel? Or is that to weird.
