ex problems

i haven't seen my ex in over 16 months. i left him for my current boyfriend who i'm happy with. but i can't get my ex out of my heart. now, before y'all go crazy bc i left him, he wasn't the greatest. he took care of me but he broke my heart multiple times. he left me for and cheated on me three times with the same girl. my parents hated him and i wasn't allowed to see him at all. not even at school, even though i did. we dated off and on for two years and i snuck over to his house and out of my house sometimes to meet up with him. i miss him a whole lot but my boyfriend hates my ex and won't let me talk to him for closure. my current boyfriend doesn't know that i've been on my ex since about 3 months in of me and him dating. we didn't exactly end things well so there's no closure that either of us have. what can i do to get over him? it's really messing with my life and the way i act around my boyfriend. how do i get over him?
