"First of all, you won't even let me say a word. Second of all, we have a house to do," Tarek explained. "What's the real problem then? Tell me."
Christina replied, "There's absolutely nothing going on with me. I'm talking about designing the patio and you always interrupt."
Ultimately, Tarek confessed that he doesn't really appreciate when his ex teases him about everything from his dating life to his new facial hair.
"You keep asking me about dating, you keep prying in my business, and I just want to be left alone. I can't come in here and do my job when you make me feel uncomfortable," he explained. "You make me feel uncomfortable. When you do that, it throws me off because I just want to live my life. I want to come here and do my job and I can't do my job if you don't let me talk, if you storm off. We're trying to fix a house. We can't do any of these things if you're gonna act like this."
Soon after, Christina realized she may need to lay off on the teasing—even if she doesn't mean any harm.
"Sometimes I forget that I can't tease Tarek the way I used to. And maybe it's a coping mechanism for seeing him out there on the dating scene. I don't know, it's all new territory," she shared before calling a truce. "I totally understand what you're saying. I should respect your boundaries. I swear I was just joking. I was just trying to make light of it. I won't do it again."
