In the next episode of MTV's "Teen Mom 2," things start to get serious between Chelsea Houska and her new boyfriend Cole DeBoer. Houska dishes to her friends about plans for DeBoer to move in with her and her daughter Aubree in a new sneak peek.

In the clip, Houska brings Aubree with her to meet up with friends for lunch. One of Houska's friends asks Aubree about her recent graduation from preschool, and Houska tells her friends about her recent exchange with Aubree's dad and her ex-boyfriend Adam Lind, who almost forgot to attend his daughter's graduation ceremony.

"Before her graduation, I had told Adam about it and I was like 'he's gonna forget,'" Houska says. "And I get a text from him and it's like 'how can you not tell me about her graduation.' I scrolled up like one text, screenshot and sent it back to him and I was like 'I did.' He sounded like such an idiot."

But Houska isn't letting her ex get in the way of her happiness with her new boyfriend, DeBoer. The couple has been dating for 10 months, and they're taking big steps in their relationship, like getting a pet pig together in a previous episode. Houska reveals that DeBoer is planning to move in with her and Aubree, and little Aubree has plans of her own when it comes to DeBoer.

"Can I tell them?" Houska asks Aubree, and her daughter nods yes as she colors with crayons. "She said that he wants to call him dad when he moves in."
