guy problens

so there’s a guy who i used to talk to all the time, i told him everything, we were so close, he asked me to go to a movie with him twice and we told eachother all the time that we loved eachother and then the other day we got in a big fight and he said that he never “fully” liked me. i was so heartbroken and we didn’t talk for awhile. we finally got back to talking but it just wasn’t the same. i just heard from one of my best friends that he has a new girlfriend. i am so heartbroken and i don’t know what to do or how to move on.
