Break ups😭

After a year and a half he broke up with me. It was over text and real immature. "I'm sorry I'm done I've been thinking a lot and we're just not working out" that's it blocked me off of everything it was done he has no emotion over it he's already liking and txting other girls. Somebody please just give me advice or a pep talk. I feel like nothing now. He told everyone things weren't fun anymore. I lost my virginity to him😭
