After moving in together a few years back, Ortiz-Magro revealed that he was given a \"timeline\" to either propose to Giancola or split.

\"I got cold feet,\" he explained on the show. \"I ended up cheating, she found out. I blew it, it’s over.\"

Ortiz-Magro spoke to People magazine about Giancola not returning to the show.

\"On the one hand, it sucked because we all started this together so we wanted to end it together,\" he told the magazine.

\"But at the same time, it worked out better for me because it was just less drama for the house,\" referring to the couple's frequent arguing on the previous show before they split up. \"Who really wants to live in a house with their ex? That’s just the most uncomfortable feeling in the world.\"

Although she has moved on, Ortiz-Magro said he and the cast still stand by her.

\"She has a boyfriend and she’s really happy and that’s a decision that she made,\" he said. \"And us as a family and as castmates and friends that have known her for so long, we’re just going to support whatever she does.\"

In addition to being back on the show, Ortiz-Magro welcomed his first child, a daughter, with girlfriend Jen Harley earlier this month.
