Avoid the use of "got" in this situation. "If you hadn't texted me that day, we would never be together"

Hello Both are correct. Well done! Adnan

Definitely the second sentence, but I believe UK English speakers use the word "got" instead of "gotten". Just something to keep in mind when listening to opinions about what sounds better. In any case, I think the second sentence sounds like a perfectly natural way to express the idea. Maybe there's a shorter way to say it, but to me it sounds short enough to express the idea involved. You could also say "... ever have... " instead of "... have ever...", but it's a minor difference.

Use "never" ... "If you hadn't texted me that day, we would've never been together" or "If you hadn't texted me that day, we would've never gotten together"

Agree with Debra Wilmar, the second definitely.
