The guy [25M] claimed that he loved me [25F]

I am 25F, from a small town in India. I had recently shifted to abroad for studies. Back in town there was a guy who really liked me, and did everything for me, things i never thought someone would do for me. For almost 6 months hw did everything for me. He claimed he loved me. When i about to leave the country my bf and i ended our relationship, and this guy really wanted a chance to be with me. After a month and his constant trying i decided to give him a chance. But as soon as i made him realise that i will be with him and love for few weeks he was fine, but then he snapped. He stopped putting efforts, stopped listening to me always putting other above me and even he erased everything he had related to me on insta. Whenever i confront him about his behaviour he thinks i m fighting and he gets angry on me. I cried a lot infront of him, even when i went to prague i begged like a fool from him. I kept crying and crying. But it feels like he is just done with me. Even shouted on call infront of his friends that he doesnt love me. He saya they are very important and i should accept that fact. He doesnt texts or reply or picks my call when he is with them. Now i m in a unknown country, crying day and night, and dont know what to do. I even said lets be friends, but even as friends he is treating me like shit. I am not able to understand what is happening. I am very lonely, as i made him my universe and stopped talking to any other people. Its getting very hard for me.

What to do?
