I normally only initiate texting to make dates. But I have a girl who I recently slept with who text me everyday. Ive run out of the "I'm busy" type texts that I use after a couple normal replies. What are some good general rules and principles of text game. But also what should I do in my situation when I really don't wanna text because it never helps me .

I'm 22 she's 19. She's always on her phone so I'm stuck here
