Adam Lind's ex-girlfriend, Chelsea Houska, was disappointed in his daddy fails during last night's Teen Mom 2.

While chatting with their daughter, 6-year-old Aubree, Houska discovered Lind wasn't stepping up as a parent in the way her fiance, Cole Deboer, has.

When Houska’s mom asked Aubree if she was looking forward to DeBoer “playing games and doing all that stuff that dads do,” Aubree said, via Radar Online, “Except my real dad. He doesn’t play with me. Cole will.”

Right away, Houska broke down.

“If I were to bring it up to him and say, ‘She said this, she’s hurt,’ he would blame it on me,” Houska told her mom. “No matter what you say, it’s not his fault. She’s going to feel like she’s not good enough. Don’t be a piece of s**t.”

“Why not just go away. He’s only making things worse,” Houska continued.

Plus, added Houska's mom, Lind's failure to participate in his daughter's life in the way the family has hoped is likely having a negative impact on her each time they are together.

“You think him going in and out, and her going there and he sits on his phone and ignores her is better for her?” she asked.

Last month, during an interview with Wetpaint, Houska spoke of her ongoing tension with Lind, addressing whether or not she thought she could ever trust him completely.

"It’s going to take so long, I don’t know," she admitted. "There are things that happen where you think it’s getting better and then he does it again, it’s kind of up and down. As for our custody agreement, you’ll kind of see all that play out in the season so I don’t want to get too deep into that, but you will see that storyline."

Teen Mom 2 season seven airs Mondays at 10 p.m. on MTV. Check out a sneak peek of next week's episode below.
