my first breakup

We dated for 2 years and 2 months, I find out he cheated on me for a year and six months. I am so heartbroken. But I'm not mad that he cheated, I am just sad that we are no longer together, I am sad that I lost the person that I think is the love of my life. But idk if he really because he was my first boyfriend. But I want him back I want to be with him, I feel like such an idiot.
