We aren’t even sure what’s going on. Let the OP clarify. There are multiple ways to message someone on Reddit and they did not comment on my picture and they did not send me a message, they sent me a personal chat thread that I had to except or decline to continue the conversation with them -

And the message came either in the middle of the night or early early morning buried with other compliments from the thread. If it’s the guy, I stand by what I said. If it’s her, my bad, was trying to look out for a fellow female by posting this on a thread she might see. And if it was him, then unless they’re in an open relationship he shouldn’t be acting that way
