How do you get over a breakup?

So i broke up with this guy sometime during january but i still cant get over him . There was some physical/emotional abuse but mostly emotional but the physical abuse wasnt very serious just a few slaps and shoves..but i broke up with him because of the emotioal abuse. But he claimed that he wouldnt have acted like that if i were more loving, like kiss him without being asked to and telling him i loved him more . But since we broke up we try to be friends but we get into arguements sometimes and its like off and on with us. I just want to get over this break up already but it just really sucks because i know we both couldve been so great together if we wouldve changed our habits. So i guess my question is how do you move on?
