Dakota in Season 3 is accused of having an emotional/sexual-texting “fling” with one of Taylor Frankie Paul’s longtime family friends , not a random outsider or castmate. The show and coverage never clearly name her on-screen; she’s described as a woman close to Taylor’s family who shows up at holidays and gatherings, which is a big part of why Taylor views it as such a betrayal.

What actually happened in Season 3?

  • The situation comes up on Season 3 of Secret Lives of Mormon Wives , tied to Dakota Mortensen and Taylor Frankie Paul’s on‑off relationship.
  • Dakota says it happened while they were “broken up,” so he insists it was not technically cheating, but Taylor sees it as a serious breach of trust.

Who did Dakota “cheat” with?

  • Multiple recaps and reunion breakdowns describe the other woman only as a close family friend of Taylor’s, someone who’s at Christmas, family events, and around them a lot.
  • At the reunion, Taylor confronts this friend with her mom; the friend denies having feelings for Dakota and downplays intimate photos as just swimsuit pictures from a trip.

Because the show and major write‑ups avoid using the woman’s full name, most discussion online just calls her “Taylor’s family friend” or “her mom friend,” and that’s as specific as publicly available info responsibly gets.

TL;DR: In Season 3, Dakota is accused of sexting and having a flirty connection with one of Taylor’s long‑time family friends, which Taylor considers cheating, even though Dakota claims it happened during a breakup.
