The quickest way to get over a
break up is to make sure
you have zero contact with that individual. That means, no looking at their photos, reading their letters/emails/texts that you've saved, no trips down memory lane of all the fond memories you shared. Do you best to avoid that person and not run into them or be at places you know they are going to be. Once you've done that, start spending time with friends, or make new ones. Get yourself out there and start dating casually.
