is texting considered talking?

if you have been texting someone for over a year and never talk to that person on the phone and someone asks you if you've talked to that person would your answer be yes or no?

I just found out my boyfriend has been texting his ex-girlfriend for over a year behind my back and claims he's never talked to her on the phone. A few months ago when I asked him if he had talked to her... his answer was NO...never mentioned the texts between them and says his answer to me was not a lie. I'm beside myself and my thoughts are killing me.

I'd love to hear your thoughts...
