If it's any consolation, I can say that when I broke up with my partner in 2007 after several years together with plans for marriage, it was an anxious time for a month and a half but gradually rediscovering myself and living more confidently and independently was the best thing to have happened to me. Our relationship started with me basically on the pedestal and him doing everything to court me and ended in the exact opposite, with me trying to keep him. In retrospect, it was pathetic of me and a far cry from who I'd been before I met him.
