IIRC she WAS sent to prison for several years, and when she got out, him then being of age, they got married and have been so ever since. They are different than most people/cases.
You remember right. He went to court to reverse the no-contact order, married her, raised their two daughters to adulthood and neither they nor he has never been in trouble. That’s some pretty astonishing commitment from someone whose romantic relationship started before he was old enough to vote.
Personally I hope they are together for many more years.
