I left him..

Okay so basically I broke up with my ex boyfriend on Wednesday. We were together for a year and 3 months, but whole year he cheated multiple times . Hung out with a girl , talked to them on Snapchat and Instagram and commented on their pictures. He actually let the girl he hung out with take pictures of them and I found out because my cousin followed her on Instagram and he told me . After the 3rd time I slowly lost feeling for him . Then the last 3 months he would yell at me out of nowhere, start tripping on me when I went somewhere like he couldn't trust me . I was never able to do anything when I was with him . So i finally broke it off and now he's a mess . He came to my house at least 5 times already these past 2 days because I blocked his number and tried to beg for me , cries , asks thousands of questions and i start to get irritated a bit because of all of this . I gave him my reasons and left it at that and he proceeds to try . I don't wanna sound like a bitch about it but he hurt me way too much . I can't be with someone I don't trust. Am I a bad person for this ?
