I don't know you sleeping with him? If yes then he's not just a friend biological chemicals during mating change that no matter how casual you think it is... and if no then 60% he's into you and wants more than to just be your friend 40% he drunk and just busting you for fun

I dunno it's one of those things, I'd say it was curiosity since I'd do the same with any mate of mine. Then amp it up a bit if they're being evasive about who it is (and if I'm drunk I won't have the sensibility to stop bugging ya). However it could also mean he's looking out for ya or is a bit jealous of the texter.
