Out of 7 seasons of The Bachelorette and 15 seasons of The Bachelor, this means the show is 3 for 22 in creating lasting relationships. That's a 13.6% success rate. Currently, the Bachelor franchise has produced two weddings (Trista and Ryan Sutter; and Jason and Molly Mesnick) and one couple is engaged (Ashley Hebert and J.P. Rosenbaum).
Ali sent home Chris Lambton before the final rose ceremony because she had fallen in love with Roberto, and honorably did not want to put Chris through additional heartbreak. This was a move never before seen in the history of The Bachelor or The Bachelorette.
After meeting in 2010 on set of the reality TV series, Ali and Roberto got engaged and moved in together, making public appearances both on the red carpet and at Bachelor-hosted televised events. Despite the unconventional start to their relationship, Ali and Roberto appeared to be happy and in love, and were one of the show's most promising couples.
The next season of The Bachelor will star Ben Flajnik of The Bachelorette (Ashley Hebert's season). The series premiers on January 2, 2012 on ABC.
