We broke up 15 months ago after 4.5 years together. The breakup was cold, callous and I felt discarded. I'm over the heartbreak stage now but still think every day of everything that happened. I have to go to the area where he lives occasionally for work, but thankfully haven't bumped into him yet. Is it normal after 15 months to still think of things, even though I'd never go back? I've done a lot of work on myself and have been getting out and about, but I still feel an underlying sadness/ melancholy at times. I've no interest in dating.
