The term "Texted" is an incorrect past tense representation of the verb, or of the referenced noun text. The verb text has always been past: text, Present: (text later with cell phones texting, showing present form), and Future: text.

Incorrect language: we had texted.
Any competent English teacher can tell you what is wrong with that statement.
You do not use the past perfect in a later action. Please ask a credible Professor.

The term texted is a term made up in the later 1990's to early 2000's. It was a slang used by some whom did not understand tense in the English language. Putting in Wikipedia and others, till they repeat/accept it, does not make it correct language.

Yes, I understand, the English language isn't easy. We All make mistakes! It would seem as a natural progression to just add "ed" to the end of text thus creating texted. However, that addition is in contradiction to the basic rules of English. If teachers of English would have been more educated in the texted orgin, they would have fixed this before it started.

Thanks for listening, all education can be difficult, and the English language is one made more so, because it is the melting pot of most languages on the planet.
