So there's a girl and she always texts me with "heyyy" or types my name as "Calebbb"? Any advice on what it could mean?

Is she being friendly

Is she flirting

Probably just emphasising how she would say it in real life, trying to be extra.
Heyyy is a dragged out Hey.
I wouldn't call it flirting, more leaning towards friendliness.

Or maybe she wants something, like a favour.
Depends what was said next.

I see the extra letters as her flirting with you. Imagine her saying that in person. She’s flirting with you.

She sounds like a country bumpkin am I right?

[Iron_Man]

Not that fat grotesque, kind the different kind

[katiesmuff]

She is really bad at spelling!

[humanearth]

Sounds like a friend

She is drama. She doesn't take you seriously
