My ex of 4 years met a girl a few days before he broke up with me. He admitting to messaging her the day after and less than 2 months later they were 'Facebook official'. The reason we broke up was because he was unhappy, when he broke up with me this was the first I'd heard of this. He was still telling me he loved me and missed me everyday prior. We had spent the last year and half as long-distance which was tough but we still spoke every day and had a plan to be together permanently soon. His new relationship is also long-distance. He is already introducing her to everyone and telling them she's 'the one'. Could she be a rebound?
