I need help

So my boyfriend and I broke up. We're on good terms and we still talk. I've been talking to him a lot, about just life and stuff. We were together for a little over a year, and he broke up with me because he said he wasn't in love with me anymore. This was my first relationship, we've known each other for about 5 years, he'd actually liked me since he'd met me. But I wasn't ready for a relationship and so we just stayed friends. Fast forward to October 2017, I told him I had feelings and we'd talked and got together. I wanted to date him, not only because I honestly did have some feelings, but because I thought it would be safe, he'd loved me for years he wouldn't leave me. But then we got together, and my heart just fell for him, he was my whole world I would do anything for him. I was so in love, and I was so incredibly happy. I didn't think I would love him as much as I did, but he was my everything. So fast forward to the end of January, we break up. It was devastating for me, for a bit. I cried some, mostly because I did love him so much and then I put on a brave face, telling everyone including him that I didn't have any romantic feelings for him anymore. That I was okay with just being friends, and talking to him still. Even though, he doesn't ever start our conversations, or ask about me or anything, and he never put in any effort or tried to communicate to me in our relationship, I mean his work was literally two turns away from my house and he couldn't spare a couple minutes to come see me. He gave me a promise ring and two weeks later, left me. I'd only get to see him on the weekends and he barely talked to me during the week. He technically cheated on me, and I still stayed with him. And I keep telling myself I'm so fine with not being with him, even though he's all I think about. Every second, I miss him so much. He was my best friend and I haven't seen him in about a month. The whole year we were together, even though I didn't see him much we never went 2 weeks without seeing each other. But I also know if I see him I know that I'll want to just run up and hug and kiss him. I'm not sure what to do, because I just miss him and I think I just have such a deep love for him, even though I tell everyone I don't. Please help me because I don't know if I want to just cut him off, I feel like that would hurt worse I don't know what to do 😭💔
