In conversation withactor and casting director Eliza Roberts andToday’s Jill MartinonThe New Rules, the pregnantSelling Sunsetrealtor, 35, talked about building a healthy relationship with husbandTarek El Moussa’s ex-wife,Christina Hall, with whom he shares son Brayden, 7, and daughter Taylor, 12.

“I haven’t talked about this much because I’m a very happy, positive person, but I felt like I was always second,” Heather candidly shared.

“No one ever made me feel that way, but I think when your significant other has such a long relationship with the previous spouse and a lot of love — and it was a very public divorce and you’re coming into it. You fall in love with each other, but you always kind of think of the ex. For me, I did,” she continued.

“I mean, we’ve definitely had some ups and downs,” she added. “They had ups and downs.”

“I think she realized how much I love the kids and that they are number one to me, over anything. So any drama aside, the kids are the most important thing to all of us,” said Heather.
