I was dating a guy and we really clicked. We ended back in January, he blocked me on social media, and then unblocked me in Late April, and wrote to me to congratulate me on graduating. I said thank you, and we stopped taking again but reconnected and have been catching up. He even apologized for being the way he was. We're friends but everyone says that him and I must still have feelings for each other considering that we have a past, and two people who once had a thing can't be friends unless they still like each other. Is there really truth in this?
