What does it mean when a guy used to use a lot of smiley faces when texting and now just uses the tongue face?

When a guy shifts from using a variety of smiley faces to primarily using the tongue face, it may indicate a change in his mood or feelings towards the conversation. The tongue face can suggest a more playful or flirty tone, possibly signaling that he's feeling more comfortable or cheeky in his interactions. Alternatively, it might reflect a desire to simplify his texting style or a shift in how he wants to express himself. Overall, the change could point to a transition in his emotional engagement or intent in the conversation.
