I have to say that I’m not a psychic, but I think it’s obvious this person has moved on. You were the only one who felt the connection. If he had felt a true connection to you, he wouldn’t have gone back to another. It hurts, I know, but do yourself a favor and try to find someone who will be there with you and for you. Take relationships slow. Don’t jump in too quickly, especially with physical intimacy. Men enjoy the chase.
