Why did he signed off suddenly without asking me a permission?

Maybe he likes you just on a friendship term. Don’t press the matter if it’s nothing big, you may go further with him and he may come to like you as more than a friend. But he doesn’t seem to me like he’s into you like that. So don’t fret, just ask him next time you see him online. :) He shouldn’t be too mad, just don’t come across as clingy.

have you even told him YOU like him? probably not so if hes teeling you about another girl he sees you as a friend …JUST a friend because you havent made it clear that you like him as for signing off, he doesnt have to tell you your not dating or married, you just know each other its perfectly fine to forget or even do it without asking its the internet, its not like your talking in person which is more meaningful

Why did he signed off suddenly without asking me a permission?

Are you serious? Like seriously? You want someone to ask your permission to go to sign off? Now, fair enough, it isnt the most considerate thing to do. But PERMISSION? Who are you, his drill sergeant?

Then when I told him to sleep. He signed off

You TOLD him? Ok, lets put the wording aside. He’s told you he’s sleepy, implying that he’s going to bed. He’s oh so kindly been granted your permission, and now you want more? The poor guy. I mean seriously, there are limits to how high maintenance a person can be.

He’s still around despite your demands, the guy must either like playing games or really like you. As to the answer to which it is, who knows.
