How do you guys advise me getting me over the betrayal aspect of my breakup?

Hey guys so my ex broke up with me after we were together for four years. He left me in a very low moment. He knew this because I shared my struggles with him for months and months, cried day in and day out only for him to leave me two weeks before the biggest test of my life. I shouldn’t be exactly shocked, Over the course of our relationship, he broke up with me 10 times And I never once left him or even threatened the idea. Last time he broke up with me, I was so hurt that he could leave me To suffer while he went out and Lived his life. I decided And told him I did not want to be friends and I don’t think he should contact me. It’s been four months. I’ve made tremendous progress, but one thing I can’t shake somebody who said they loved me can Leave me, when they know how low I was. Any thoughts? When these feelings arise, I sit with them and try to process them so I can move forward but a little advice would help thanks
