Sadly, Sam Smith has proven that he is, indeed, too good at goodbyes — he and boyfriend Brandon Flynn of 13 Reasons Why, who had been dating since October, have broken up, according to The Sun.

A source told the site“Sam and Brandon had a real whirlwind romance. They really fell for each other. But they are both so busy with their careers and unfortunately things just haven’t worked out. Sam is obviously devastated. This is the most significant relationship he has ever had."

Both have unfollowed each other on Instagram (a millennial tell that things are, indeed, over) and Smith has scrubbed his account of any evidence of Flynn.

According to People, Smith seemed distraught at his Brooklyn show Wednesday night (June 27), telling crowds: “I’m going through some s---.”

Though the couple were first spotted kissing in October, they didn't publicly confirm their relationship until December with a photo of them traveling in tandem unicorn pillows.“Rare sighting in London,” Flynn captioned the pic.

Flynn has since said of Smith: "At 26 he’s accomplished so much. He’s an angel! He makes me so f------ happy."

And fans seemed devastated by the breakup. "Omfg please don’t do this. FIGHT FOR LOVE," one wrote in the comments section of Flynn's Instagram, while another noted "it sucks...i love them so much...just don’t believe in love anymore."
