The 'Stay With Me' hitmaker said he made a mistake in getting the public involved too quickly, reported Evening Standard magazine.
"Nothing dramatic happened. I made a mistake by posting pictures of us on Instagram and making it seem more serious than it was. I flew him to Australia and we had a nice time... We just weren't very compatible, but I've learned that I need to hold off before I start getting the public involved.
"I would say it was a relationship, but I still feel like I haven't had a proper boyfriend yet," he said.
