What does this mean?!

Long story short, this guy has been my friend for years and we almost dated. He’s sent me mixed signals and been playing games about whether or not he wanted another relationship etc. so everyone has advised me to stay away that he was only hitting me up when he was bored or for convenience. He texted me last week after not talking for a few months. Fast forward to last night...

I fell asleep before 11 last night and when I woke up, I had a text from him out of the blue saying “go to sleep”. When I opened it this morning, I just laughed and said I was knocked out early. He didn’t say anything back. What the heck do you call that??
