Jordon Hudson penned an emotional letter to her cheer team after making the decision to quit ... and in the note, she issued an apology to her squadmates for all of the hoopla her relationship with Bill Belichick caused.
The message -- which was obtained by The Washington Post -- appeared to be sent this past winter ... after Belichick had accepted the UNC football head coaching job.
Hudson explained to her teammates she would no longer be flying for ECE Blackout in Massachusetts -- as she was going to follow her 73-year-old boyfriend to Chapel Hill.
