What doses it mean when a girl says stop sending me these novel text messages
It means you're rambling on and on and on and on and on ... and that you're not important enough to her to read these long "books" that you call text messages.
that there dummn and useless
They are too long
Your texts are long, like a novel
Your texts are too long! If you want to talk to her, do it over the phone, or in person. Texting is a bad way to communicate.
Stop means stop, halt, desist! In other words DON 'T TEXT HER
It means stop sending her long text messages. If you have to text more than 2-3 sentences, you should probably find a different way to communicate with her.
You are saying too much
it means she wants shorter text messages..... duh
It means you talk too much to her and spend too little on her.
