Well, you can say many things:
Call me
need 2 tlk
Heyyyyy! Wuzzup?
Meet me ______ (your house, school, etc)
Luv Ya! What's up
Hey hey hey did u hear about what happened today
It means that they aren't interested.
I'm pretty sure it means you're a stalker.
that means probably her 2nd option.
Don't text them anymore
he likes u but he doesn't wont his mates to know (he has a secret crush)
so have you!
I want your body
No. If you know he saw your text and didn't answer it, do not text him again.
That this number has been disconnected, that the text did not get to the number, or you won't get anything back.
Be confident, and go ahead and text him! but make sure you don't double text him in the amount of time it would take him to have a nap. unless your finishing a thought or he texts back.
I think you should say you love her back
if its a guy then he is afraid of rejection so i say you should say it first then he'll say it back
