A man I was starting a relationship with (or so I thought) ghosted me 6 months ago. Yesterday he randomly wrote me a text message saying he had been thinking about me. He apologizing for disappearing and acknowledged that it "wasn't cool", but gave no explanation as to why he did it. He said that I didn't have to respond and then brought up memories of our first conversation before ending the text.

So far I have not responded. I don't know how to or if I should at all.
