Please help..I cant take the pain anymore...

Hi, I am feeling so bad and empty for the moment and I thought maybe someone of you could help me? (thanks in advance!) So, I was together with a boy for almost 2 months. Previously, he was my best friend for more than a year and we were like twins. We looked like each other, had the same character, almost everything was the same. He was perfect. Everything was perfect in our relationship, we knew each other the best. But then suddenly, he said his feelings went away. 5 days before,he said he loved me. We were very comfy with each other, we both had the feeling that we were the ''mr/mrs right'' for each other. However, I cant stop loving him. He's in the same friend group as me but he seems like he ignores me. However, when he broke up he said ''I like you so much and you're so perfect but my feelings went away'' I dont understand this at all.. what would you do? I cant forget him, he meant so much to me and he always will.. but he keeps hurting me that way. It looks like he lost interest. I feel so empty and my heart hurts alot. I never experienced such pain... he's in my school / friend group as well so its very harsh..he keep ignoring me.. (we broke up around 3 weeks ago)
