Why did she mean by " i stopped talking to her" read on....!?

so me and this grl hooked up online almost 2 months ago,so we text often and we talked on the phone few weeks ago. on vday she called me asking why i stopped talking to her, and i was like ewell i texed u few days ago...apparently texting to her is not the same as talking?? she said the last time we "talked" was few weeks ago which was when we talked on the phone. i thought text and phone were not so different. im lost!!1
