What’s this reply mean

Sent the boyfriend a booty pic and boob pic today and all I got was a “that’s nice” reply.

WTF does this mean? That he doesn’t care?

UPDATE

So I called him after the text and said “That’s nice, that’s all I get”?

And he said “Babe I’m working”

So I let it be. We got into an argument and I said “well I’m gonna stop sending you pics, you never responded to them anyway”

And he “No you don’t have to stop”

LMAO
