Break/up 😥😢 Advice PLS 😩

I kept texting and calling him and he's not answering. I've texted him today and asked what happened, or did I do something to upset you. He said he's talking to someone else now. Like you have been dating me for 7 Months and just up and leave me for someone else??? I don't understand, why someone would do something like this! Like I just fucking lost my virginty to him. I feel like such a dumb ass, for thinking that we actually had a strong connection. Idk what to do at this point. And I've gave him my other iPhone that I had. PLEASE I can't stop crying. I usually don't do that for people that I date or talk too, he really made me feel like we had something. How could someone be so heartless 😢
