Me (F28) was dating a guy (M25). He approached me. He was very open about liking me. He asked me to be exclusive (girlfriend – boyfriend), he introduced me to his friends as his girlfriend and he told me he was very in love with me. He plans for the future with me. Everything seems fine and I’m really excited. Then he tells me he and his ex had a talk and she said she wants him back. He feels like there’s something holding him back from giving me his all and says that he feels like he rushed into a relationship with me… so here I am – single again. Heartbroken and wondering what I did wrong
