I'm going to forget to text back my gf
Why do you want to ignore her?
She has been mean to me lately and I am pissed about it.
I understand that you are upset about your gf being cruel to you, but cutting off text communications is inconsiderate. Answer her back and find out what she wants.
She's an idiot, I'm going to ignore her for a week or so.
I think that that is just going to worry her. It is not okay to ignore her texts for that long of a period.
