Chelsea Houska's ex-boyfriend, Adam Lind, majorly disappoints their daughter, Aubree, during Monday's new episode of Teen Mom 2.

Ahead of Aubree's father-daughter dance, Houska is unable to make contact with Lind and enlists her fiance, Cole DeBoer, to take her to the school event.

“If your dad doesn’t call or anything, you’re okay with going with just Cole [DeBoer] or do you not want to go?” Houska asks her daughter in the new sneak peek, shared by Radar Online on Friday.

“I want to go,” she responds, explaining that she'd prefer for both Lind and Deboer to attend because DeBoer is her “other daddy.”

By the time Aubree needed to leave for the dance, Houska still hadn't be able to contact Lind and DeBoer and the 6-year-old prepared to leave.

“Where’s my dancing partner?” DeBoer asks Aubree as they take photos together.

Houska and Lind have faced co-parenting issues for years, and currently, they are in the midst of a custody battle which Lind recently ranted about on Instagram.

“Chelsea won’t respond or cooperate without a lawyer,” Lind wrote in March, according to The Ashley's Reality Roundup. “And she’s also trying for more child support. She feels $975 a month is necessary. Guess her lil pig, 6 dogs, new Jeep and house just isn’t enough and needs more extra money. Court it is.”

“Child support isn’t set by Chelsea, it is set by income,” Houska's father, Randy, fired back. “[Adam’s] been paying $170/mo for 6 years, same as an unemployed dad…Someone paying lowest allowable child support for 6 years and making ‘big bucks’ complaining about having to man up and pay? [Adam] invested more in a Corvette in one month than he has paid in child support for his entire child’s life.”
