Help me please :/?

I was daring this guy for a year i was so in love with him because he was my first boyfriend he broke up with me in September after i asked him about a girl that he said was a “friend”
Even after we broke up we were still texting casually then in February i found out he was cheating on me the WHOLE time with that same girl
When i found out i felt heartbroken and betrayed but after some time all i felt for him was disgust but now i feel so angry that I’m starting to miss him and I don’t know what to do to completely get him out of my head I’m so tired of this!!
Help me please :/?
