It happened to me during my online dating times that I talked to a person once and then decided not to talk anymore, maybe they thought I am a jerk too. He maybe changed his mind. I don't think rejecting someone before even meeting them makes one a jerk. Or he might be married. When he refused to give his number and suggested some other venue (Kik?), it was a red flag right there. Who really knows. Don't let strangers upset you like this
