Why did he come back into my life?

The guy I was seeing over a year ago messaged me. He told me he's going through bad break up and wanted to talk. Once we started talking about his break up with his ex-girlfriend, he said he has feelings for me.

We started seeing each other for about two weeks. Everything was fine until one day he told me he wants to be friends only.

I said I needed to think about it. Why would he mess with me like this? Why would he say he has feelings for me only to turn around and say he wants to be friends.
