What does a :) single text mean from a girl?

[JoshMa]

Worked together for a brief time at a job but nothing too deep. We text here and there to say whats up and catchup but one conversation that went on for 3 hrs back and forth lead to a :) which have never received from her any meanings?

I would be bored after 10mins of texting never mind 3hours. She must like you and just wanted to end the conversation with a smile.

I don’t think she was being rude or that she’s not into you.

Possibly that she enjoyed the conversation and feels better. Send a "confused" emoji back, or the one that looked deep in thought

Most girls use the 🙂 emoji when they have nothing else to say... I think it's like a universal thing lol

She's probably just not into you? Or she hates texting.
