How do I tell the perv in my inbox I'm tired of talking without being mean? I will need him later when I'm super lonely.

Just stop messaging him back. He'll still be there when you log back on.

Try the truth. Manipulation wouldn’t be cool.

Tell him to hold on you're going to take some nudes for him and then log off. Next time you log in say you fell asleep lol

Just tell him you’re busy chatting with more interesting people and he’s on the way back burner

He probably won’t mind if you tell him the truth haha

How about, "I don't want to sound mean, but the only reason I talk to you is because sometimes I get super lonely and use your perviness to temporarily satisfy my need. Outside of that, I don't care to talk to you. And right now, I'm not feeling super lonely. I'll let you know when I am. Until then, don't message me, I'll message you."
