Michael and Bella: Season 3
They decided to stay together, despite Michael's doubts about Bella's commitment. Bella told Michael she was totally in love with him, he reciprocated and they both said they "150 percent" wanted to stay married.
They aren't together. The pair split a few weeks after the show finished filming, with both Michael and Bella citing their different lifestyles as the reason for their split. No hard feelings, though — Bella says of Michael, "He's amazing, and I just wish all the best for him and hope that he finds his true love." Well, then.
