If the guy you’ve been doing for three weeks suddenly asks you when you would start thinking about moving in together, what does he want?
Predator? You’ve so overwhelmed him with your sexual and intellectual power that he can not stand to be separated from you for even one nanosecond? Just remember to gag him next time. No weird questions.
Prey? His ex is probably in the process of kicking him out, his daddy doesn’t love him, he has no money, and sees you as a kind of sugarmommy who’s going to take care of his sorry ass. Run, run for your life!
