Confronting Our Roommate's Girlfriend

I was in, um, I was in New York, and it was like, it was late night in New York, and I got a DM that said, if you're reading this at 1:56 AM, it's a sign. And I read it deadass exactly at 1:56 AM, and I was like, what is this? What does this DM mean? And I showed it to everyone in the car, and the DM DM was sent 2 hours before that. So it wasn't like I just read the freshest DM. It was like I was scrolling through my DMs and there was one that said, if you're reading this at 1:56 AM, and that was the only DM that that person sent. So I responded to that person. I was like, what is the sign? And they didn't respond. And for the last 2, 3 days, I've just been left. I don't even think they've read it. I've just been left there and I don't know what the sign is. And I've scrolled through the DMs with this person. I was like, okay, let's see what they've sent me before. It's a guy. And the last 4 DMs before that are, I want to fuck your brains out.
